It would be more of a sequel to 'Batman Begins', 'Batman: Gotham Knight', 'The Dark Knight', and 'The Joker Blogs'; and it would be a two-parter.

Part One: the Joker (played by Scott McClure) would be broken out of Arkham by Quinzel (who would don the Harlequin costume at about the half-way mark), and together the two would destroy Roman Sionis' criminal empire. Black Mask, however, would put up a valiant fight and would ware the 'Black Mask' in an effort to emulate Batman (mocking Batman's status as a criminal). Mask would ultimately be killed by the Joker, while Jeremiah Arkham, who had hired a shadowy individual to track the Joker, would take Black Mask's mask and kill the Joker in retaliation for the Joker killing his wife. Batman would then capture Arkham and Quinzel.

Supplementary details:

- Harvey Dent, Sal Maroni, and Anna Ramirez (from hitting her head on the concrete) would be confirmed as dead.

- MCU Det. Crispus Allen, Ramirez's partner and implied romantic interest, would be a challenge for Gordon and someone who refers to Mayor Garcia. With this, Gordon is forced to either hunt down Batman or loose his job.

- This investigation into the Batman's identity would involve Coleman Reese.

- The Batcave and Wayne Manor would still be introduced in my version.

- Thomas Elliot will be Bruce Wayne's physician and will be aware of his secret identity, but will be on amicable terms with him.

- Carmine Falcone will be symbolically executed by the Joker and Harley before leaving the Asylum as an affront to the mob.

- Jonathan Crane will not appear in the film, but will be said to have been released from the asylum.

- The film's final scene will feature Coleman Reese being murdered by this 'shadowy figure'.

- Selina Kyle and Bane will not be featured in this film.

- Victor Zsasz is the Joker's right-hand man, although his role will not be prominent (he will be almost the equivalent of Bob from Time Burton's 'Batman'). He will be captured by Batman at the film's end.

- Det. Gerard Stephens will return.

- Det. Harvey Bullock will be featured and will act as the Joker's inside man in the MCU. He will be arrested by the film's end.

Part Two: the League of Shadows returns to Gotham while championed by Bane, and Selina Kyle is introduced with the Catwoman persona already having been adopted. There is a bounty on Batman's head that has been set by the shadowy figure. Eventually Kyle discovers that Bruce is Batman, and begins a Romantic relationship with him to try to discover why he is Batman. They both ultimately discover that they are rogue League of Shadow recruits (Kyle's parents were killed by Carmine Falcone and she also sought out the League), and fight to stop Bane and the shadowy figure, who is revealed to be Talia Head (a member of the Wayne Enterprises Board and Ra's Ah Ghul's daughter). She has been trying eliminating the individuals who pose the greatest threat to the League's effort to destroy Gotham (the Joker and Batman) Bane is killed, but so is Selina and Lucius Fox (Head discovers Lucius is equipping Wayne). Head decides to retreat from Gotham, telling Wayne that the League will not attack the city again until a new head is appointed by the League as "(she) is too blinded by personal vendetta (Batman to kill her father, after all) to efficiently perform the operation". Bruce declares that he will be ready for them.

Supplementary details:

- A sub-plot will involve the Nolan character of MCU Det. John Blake discovering that Batman is innocent of the murders he is accused of. Though Gordan and Crispus try to create hindrances for him (for very different reasons, of course), he learns that Harvey Dent murdered those people. This is revealed publicly as it is the only way that Gordan, who was fired by the mayor for not properly pursuing Batman, can be re-appointed; and because the preservation of Gordan's role as commisioner is perceived as more important than the preservation of Dent's reputation.

- James Gordan is temporarily replaced by the incompetent, but not corrupt, Peter Pauling.

- Gerard Stephens, who only cameos in the previous film, secretly takes orders from Gordan when the city is attacked by Bane after the incompetent Pauling proves that he cannot handle the situation.

- Holly Robinson will not appear, nor will Miranda Tate (presuming she is not Talia Al Ghul).

- It is revealed that Coleman Reese was killed because he refused to reveal to publicly reveal who Batman was.

- Thomas Elliot is appointed head of Applied Sciences by the film's end.

Nice...

I was hoping that Nolan would introduce Dick Grayson as Robin, but make it cool. I know the whole B&R thing is probably dead forever (at least in film) , but if anyone can do it, Nolan can.

Hi there, I just saw your blog and I kinda like it. Especially Catwoman being a rogue member of the League but knowing how Nolan works. Why not combine Selina with Talia al Ghul. Talia is the vengeful daughter and Selina is thrill seeker who doesn't want to be held down yet both of these volitile women love Bruce to an extreme. Nolan has no doubt combined these women. Selina Kyle the cat burglar is simply Talia's way to have fun and to redistribute the money of the filthy rich to the less fortunate. She is kinda of deterring herself away from her father's draconian view of destroying everything and having people learn from their mistakes. Miranda Tate character will probably be Nyssa Raatko who has nothing but contempt for Ra's and Talia. Ra's will probably return for the sequel thanks to Lazarus Pit. Bane will probably get a dose of the Lazarus Pit like you saw in the trailer.  
 
As for Joker, you were right I felt cheated that they just killed off the Joker. Its because people are so stuck on the idea that no one can play Joker like Heath Ledger. I give Heath credit for bringing out a new level of the Joker but Nicholson was the sole basis of how to develop the Joker plus he had a better laugh. Check out a youtube clip of Joker and Harley Quinn music video with the song "My baby shot me down". It has brittany murphy as Harley Quinn and she would have been perfect. I cried the day she died because she would have been untouchable as the Harley Quinn but any good actor like Johnny Depp or Daniel Day Lewis can be the Joker. As for Black Mask, I would have saved him for a Catwoman spin off that wouldn't suck but you have to admit Halle Berry's version would have been great if they had Black Mask, Clay Face and Sylvia Sinclair in it because I think it had something to do with an addictive cosmetic plus that Catwoman costume was the best ever. Also too, check out Anne hathway's catwoman get up it looks identical to Talia's usual attire. If you want to chat some more look me up. My name is RavenVice01. Pleasure to meet you.     

@Rudyftw: I had considered for my proposal an ending for part two where Bruce Wayne receives an invitation to go to the circus (make a lucky guess as to what the main attraction would have been), but I thought the Talia Al Ghul ending was more appropriate.
