Not gonna happen. The writers and editors all agree that they didn't like the squad system for the X-Men. It creates this lotto system where several writers would want to use the same characters, creating these situations where writers have to grab whatever character they can find (even if they have no real intention of using them, or if they simply don't know how to use them) just to fill out a roster.
Instead, all characters are up for grabs. Any writer can use any character they want in X-Men Legacy, X-Men, Astonishing X-Men, and Uncanny X-Men. It just so happens that they're using all the same characters. X-Force and New Mutants are exceptions because X-Force is a secret squad with a specific purpose, and New Mutants is simply a reunion title for the sake of nostalgia. The X-Club is also a separate team, but they rarely ever leave the base and individual members of that team pop up whenever someone needs to use a scientist.
As much as I would love to see the squads return, the writers like being able to use any character they want in any given storyline too much.
