I was seeing this as an opportunity to redeem Nemesis a bit since his history of being an allied agent vs. an accidental fifth columnist are a bit convoluted. I figure the story could lay out that he's a double-agent or even a triple-agent, explaining why when he returned in the pages of Fraction's Uncanny X-Men he's actively hunting down Nazi's. The general premise is that not all of the characters would be featured at any given time necessarily, but that Earl Everett would be the anchor point for the team and the rest of them might rotate in and out. I wouldn't want to ditch pre-Wolverine Corporal Howlett/Logan because part of what I was thinking with this is that it could explain where he came up with the idea for X-Force as it was post-Messiah CompleX to begin with (though I agree that he and Mags definitely shouldn't get any more panel-time than anybody else).
