Reposting something I made for another thread:
My idea would be to somehow simplify things. Have only one main X-men team and push ancilliary X-teams like X-force and X-factor by giving them good rosters and hooks.
Each team would have its own unique roster, mission statement and base of operations. I'd avoid too much overlap and crossovers, but would keep the sense of a shared universe by having characters guest star in other books from time to time.
Overall direction of the franchise:
The Jean Grey School has been attacked one last time, causing the X-men to close the school as they realize the mansion isn't a safe place for the young mutants to live.
Meanwhile, the 05 return to their timeline and Old Cyclops is framed for a major terrorist attack and anti-mutant hysteria increases even more.
In this scenario, each team finds its own way of dealing with the crisis.
The main teams would be:
THE X-MEN
This book would focus on the family aspect of the X-men. Cyclops, one of their own is in trouble, so the team puts aside their differences so they can work together and keep Xavier's dream alive.
They'd be based on the mansion's underground complex and would get help from Jubilee, who'd stay at the mansion and coordinate missions.
ASTONISHING X-FACTOR
Angel (back to his old self) and Iceman decide to return to San Francisco and reestablish X-factor as a mutant super-hero team. The team would be trying to improve mutantkind's public image by acting as real heroes.
UNCANNY X-FORCE
X-force would be the counterbalance to the new X-factor. They'd continue working in secret, trying to deal permanently with threats to mutantkind.
They'd be based on the old Australian Outback HQ of the X-men.
