X-Men team comprised of former Avengers

Wow, this team builder took an unnecessarily silly and exclusive turn.

Sheesh.

Quicksilver was thought to be a mutant.

Lockheed is a pet.

Captain Britain I don't think really counts as Excalibur was supposed to be a "Britain Superhero Team" more than about mutants.

Cloak & Dagger, I haven't actually read whatever book they were X-Men on, but from what I've heard there was a lot of confusion as to whether they were mutants or not.

Ink's whole thing is dumb, but while he's not a mutant himself, his powers come from a mutant, so it's like...

And I think a lot of those weren't part of the main X-Men team. I mean, yeah, at the end of the day there's a bunch of non-mutants who were in the X-Men, but it's not really like it has always been free to non-mutants as well.

The point is just that you don't need to be a mutant in order to be an X-Man.

Also of those characters the only ones that haven't been a part of the actual X-Men team are Quicksilver, Captain Britain, Magik 2, and Deathlok.
