Either a new team, or an existing team getting members or retools to things you wouldn't expect. What ideas do you have?
Elsewhere someone suggested the idea of Kaine (a flawed clone of Spider-Man, with a different power set. Considered one of the few good things to come from the Clone Saga) joining the X-Force. I never even thought of it before, yet I like it. X-Force is a team of outsiders, consisting of violent anti-heroes willing to kill and do the dirty work. I feel like Kaine would fit in pretty well given that he's a violent anti-hero on the outside. Him not being a mutant could factor in the plot, with him being on the outside even with his teammates. Plus, Marvel hasn't done a whole lot with Kaine as of late.
The only real hurdle is getting Kaine to organically fit the new status quo, what with the whole "Krakoa doesn't allow any non-mutants whatsoever" thing that's currently the norm before whatever the event Hickman is building up to. X-Force, like other X-teams, have had non-mutants among their ranks in the past (Doop, Deadpool, Hepzibah, Fantomex, Spiral, and Deathlok immediately come to mind) so him not being a mutant wouldn't be an issue for the most part if the mutants shutting out non-mutants completely wasn't currently happening.
Anyways, what ideas do you have?
