I know Marvel would never do it b/c it would be unwanted competition for their own precious Guardians of the Galaxy, but if the X-men go to space wouldn't a team of b/c list X-men who go off on their own to catch bad guys be cool? Like Cowboy Bebop or Outlaw star with mutants! Who would be on your team?
Psylocke
Gambit
Frenzy
Chamber
Husk
Cypher
Warpath
I think they make a nice range of powers and personalities...
