GoG2's director is threatening us with more female characters, so I'd say Moondragon might actually make it into that film by virtue of being Drax's daughter. Or if they nix that (because comic Drax has a crazy origin), they will likely use Phyla, particularly when they use Adam Warlock.
BTW, Adam Warlock is a triple god and one of his three identities is a goddess, so I can see at least a Bi Warlock should Marvel ever go there.
Also, also no one has pointed out that Hercules is as bi as they get (the Greek pantheon in general is so open about these things). And had an AU kiss with AU Wolverine
