I would honestly save all the original academy x kids. Add in Armor and hope as well as GenH kids along with Evan Genesis, X-23.
Thats your team. Put in fucking the legion of rejected superheroes mutant kids in a containment book since their fans keep screaming for them.
That means Quire, Idie, Eye boy, nature girl, shark girl, Broo etc. This is where gold balls and bendis xmen can go too.
I mean its clear the 2000s and the post 2011 teams have two different fan bases, give them what they want.
So the X-book line up for me would be;
Main Uncanny line up. ALL the X-men belong here. You can rotate different guys each story arc like how the Utopia era did.
X-Force: Make it a good one. Our last two runs after Remender were utter shit. If its not a good pitch then drop it.
New Mutants; bring the OG team back along with the x-factor kids.
X-men Legacy: designated next gen book
Xmen Special Eds group: Aarons waifu and Bendis belong here.
You can include your occasional wolverine/havok mini series, deadly genesis or whatever stories in this section. Have a miniseries or one shot story littered here and there. Remember serve and protect? That was nice. Or magneto not a hero.
X-23 solo; fuck current laura
Wolverine: self explanatory
Gay Popsicle" He can never ungay himself. Just get him a good writer for our resident gay boy.
