Ah yes, I forgot the two main ones XD.
Plus Claremont just reminded that Lila and Gambit have history, so that could come into play.
Cannonball would be fun. I don't really remember how Claremont wrote him during X-treme but he would have to acknowledge his space job and family.
Maddie and Alex would definitely be a good addition, though I'm not sure what he would make of the Goblin Queen thing.
Another big name would be Polaris.
Thunderbird 2 would be a great pick, and I'm pretty sure he would love Trinary (come to think of it, X-men Red was a great Claremont team).
Cece Reyes could be there too.
Rogue, Gambit, Lila, Cannonball, Maddie, Alex, Polaris Thunderbird, Trinary, Callisto and Reyes would actually be a nice team wouldn't it ? Maybe a bit too big.
Plus half of them already have reasons to be out of Krakoa...
