I'd say it's time to make the X-Men a truly international organization.
Having three teams of X-Men (each with Wolverine on it) all holing up in the same mansion is problematic. If they want to spread their message across the world, perhaps they should set themselves up across the world.
I liked the idea of the X-Corporation, and I'd like for it to become more active than just a dumping ground for limbo muties.
I'd put a team of X-Men in China, to cover mainland Asia. This team would be Storm's team, minus Nightcrawler, 'cause I'd put him with the home team. So... we'd have Storm and Psylocke on this team, then we'd add Iceman, Sunfire, and Neal Shaara to finish up the lineup. Yes, I'd ditch Bishop and Rachel altogether. I'm a bit sick of people from bleak and dark futures where everybody you know and love is dead, and blah blah blah. To hell with future people!
Then our second team will be in mainland Europe. This one'll be Havok's team, with Gambit, Polaris, Rogue, and Angel. Put 'em in Paris or something, since you've got your London-centric Excalibur part trois over there doing their own thing. Of course, they'll have to run afoul of Dr. Doom at some point.
And then I'd leave Astonishing as is, focusing on the home team, but I'd add Nightcrawler to the cast because him, Kitty, Colossus and Wolverine deserve to be all on the same team again. Plus I like Nightcrawler, so I'd want him on a book I like.
