If and when X-Force allows another female to join.... who do u think it would be!! Even though it's a secret (for g-d knows how long that will last...) maybe they'll let another X-member in!? It's a possibility!!

The female has to be willing to kill.

Lady Deadpool. I know it wouldn't last, and I wouldn't want it to by any means. But just for a one-shot, just to see how the team gets driven up the wall batsh*t crazy by the DP's antics.  
 
Aaaand then probably X-23 for real? 

Domino should return.

THIS!!!!!!

Domino. All over that. She's to X-Force what Vision is to the Avengers and Martian Manhunter to the JLA.

Domino should return.

As most people here I can only agree: Domino should be in Uncanny X-Force. I've been actually wanting this since the first arc and even put it in some of my reviews.

Domino, yes. 
 
Vamp Jubilee is a strong candidate, too, seeing how she really should still need to be around Wolverine/etc. 
 
616 Blink (all evil and such?) could be drafted if/when she reforms...

I vote for Domino. I really liked her in X-Force.

Domino. Maybe Vamp Jubilee, depending on how she is on a moral stand point but since she's gonna be on the other team, I guess its not gonna happen. NOT X 23.

Domino should return. 

Storm.
 
I have my reasons.

Neena Thurman all the way.

So it's pretty much unanimously decided that Domino is the top choice but in trying to think of anyone else I thought that Frenzy would make a good addition as well. She has the right attitude and they could use someone with her abilities on the team.

I think it'd be interesting if Echo joined up, despite not being a mutant.

I think Rogue should join.

Polaris when she gets back. Illyana might be interesting to.

Lila Cheney.

totally agree with Domino. I think another great addition would be Sage

How about Elektra? I don't think she's a mutant, but she had a nice chemistry with Wolverine back when he was adjusting to his more feral state way back when, and she is willing to kill.

Domino should return. 

Aaaand then probably X-23 for real? 

Mystique would be awesome, and who is to stop her if Wolverine leaves.

@War Killer: Ah, I wasn't aware. Nevermind then!

Lila or Domino would both be good choices. I think Dust would be good just to be a good moral reflection too. She might not agree to a hit squad, but she could be the teams morals and has killed before. Actually they could explore her not scared to die side.
