Do Psionics work? I mean, it's a bit of a simplification, but ironically, one of the complaints against Psionics has been that "psychic powers are too science-fiction-y for a fantasy setting." So invert it. Take pseudo-fantasy creatures (like your alien-dragons) and give them Psionics. Because nobody's ever heard of psychic dragons.
I mean, I don't know d20 Future all that well, but if it functions anything like D&D 3.5, Psionics shouldn't be hard to import, and apart from healing, Psionics does pretty much anything magic does, with a slightly more psychic flair.
