Not to mention, let's be real here.
Considering its clear what with female Gambit, and gay male Rogue, even a Toad and a Blob who are in a way X-Men's Jay and Silent Bob. That this is fairly leinent on who you play and how. So if you looked through all of the characters who are mutants (and lord know there is a lot... A LOT of them) and you can't find any that you like in some way, shape, or form. That's on you and a lack of imagination. Hell I can drop a few off the dome all freestyle like...
One idea I considered was Iceman being a Shaun White figure, incredibly gifted snowboarder who was world famous before disappearing off the map, since he got his powers. He rides his ice waves on a specially made board that quickly attaches and detaches from his boots, allowing for transportation and a handy melds weapon.
Angel, taking a bit of a cue from Ultimate Thor, possibly May or may not being an actual angel fallen from Heaven. There is speculation, but no only really knows for sure.
Psylocke not being an actual person but a telekinetic spiritual being that travels from body to body.
Those are some just off the top of my head, give me some leg way and I'm sure I could come up with more.
Real talk...
