Here's my idea for a new animated batman series. 
 
Story takes place where Bruce Wayne, The Batman, Is gone without a trace. And in his place Dick Grayson, The first robin or nightwing takes over as batman as he along side his allies including a new robin solve and fight crime while the mystery of absence of the original dark knight deepens.

And I need your opinions 
 
should Kari Wahlgren voice harley quinn? 
and do you agree that shawn spencer and nick cutter are good choices for riddler and mad hatter?
And should Seth MacFarlane do two face, or doug lawrance? 
 
Note: This first comment is an edit of the original.

"is this just your hopes for a new series?  or is this something that's been speculated about? "

Arleen Sorkin IS Harley Quinn. Heck the character was styled after her.

by shawn spencer do u mean james roday from psych? if so, i think he could be a good mad hatter idk bout riddler...he could even be a good nightwing imo

Cool Jason vs Dick

" @daredevil21134: Hoho believe me dude, I was reading the comics staring him and boy he sure was nasty. He kills, steals, bribes, and even threatens to kill people even if they're not evil, including nightwing. "

Why is smelly Seth MacFarlane playing Harvey Dent?

" @daredevil21134: oh "

Okay now this show I thought for is targeted for audiences of all ages, mainly children (Just like with the first animated batman series) But just a hoot thou... Should Holly Robinson be in it?

I don't Know, maybe.

Neil Patrick Harris as Nightwing? What are you trying to turn this into glee. He was nightwing in "under the red hood" but cmon.... lol. This made up series sounds like the comic that's going on now.

" Neil Patrick Harris as Nightwing? What are you trying to turn this into glee. He was nightwing in "under the red hood" but cmon.... lol. This made up series sounds like the comic that's going on now. "

Sounds Awesome! I wouldn't mind a proper rendition of Tim Drake, the DCAU always seems to step over him. Battle of the Cowl is one of my favorite story-arcs and would love to watch that play out. Neil Patrick Harris or Will Friedle would be awesome as Nightwing. Though I think Patrick Warburton could lend his voice for background characters such as GCPD cops and such. 

Just edited the casting, Again.

@Bopper Girl: And it looks good. Thou I think Kari walghren should play zatanna.
