If they do go for a villain from the comics there are all sorts of possibilities:
Selene was a villain from the New Mutants period these stories seem to have used for inspiration, she's powerful and fairly interesting, so she might fit.
The Magus (the techno-organic alien monarch, not Adam Warlock's future self) again from the 80's period of New Mutants, powerful and visually interesting (though perhaps too effects-heavy); he's an alien, which might be too weird, but then again we had David remembering talking to the stars/stars talking to him in an earlier episode didn't we? So maybe that was a set-up for him?
The Shiar, again because of that whole talking to stars thing, and also because you could easily swap out Dark Phoenix for David in the original Dark Phoenix plotline, with the Shiar wanting to kill a galaxy-threatening menace.
Mastermind (and other Hellfire-club cronies), because his illusion-based powers give Hawley a chance to play with visuals and storytelling in a way he likes.
Less likely but possible:
Mojo. Often mentioned, probably too visually similar to Farouk, but who knows?
Proteus, reality-warping son of Moira MacTaggart - he's an X-Men foe from a period before New Mutants so he's not quite from the same era Hawley has been looking to, but he is not only powerful but there are a lot of parallels between him and David, what with their mothers both being old flames of Professor X and both being reality-warpers.
And speaking of reality-warpers: Mad Jim Jaspers, the Captain Britain foe from the eighties Alan Moore CB stories who popped-up in X-Men, albeit depowered, around X-Men #200 - connected to the X-franchise, right power-set for weirdness, plus a good opportunity to cast a British character actor. Unlikely but possible.
And sticking with the Captain Britain connection, mad Jamie Braddock - his string-pulling reality warping power was very similar to what we saw the Shadow King do to Walter last episode, so perhaps too similar?
The Impossible Man - probably too silly, but this "Q"-like alien would be a handful to deal with, gives good weirdness, plus made an appearance in one of the New Mutants annuals of the right era (if that is where Hawley is drawing inspiration from); and I guess Fox own the rights to him from the FF franchise deal.
I think there are a lot of possibilities for bad-guys. Hawley is playing fast and loose with the X-Men connection anyway so he'll probably just pick someone he likes and make it work.
