So. If Lee is the Scott Summers of BSG, you want to make Dee Jean. Except she isn't. No one is Jean, really, except Roslin. Which means Corsair is chasing Jean. Which kind of makes you go o.O. (Because Dad is Corsair. Hello, SPACE PIRATE. Dad is NOT Chuckles. Baltar is Chuckles, if anyone is--head!Six is his Jean Grey?)
But, if we approach this from another side...
Billy is the James Proudstar of BSG (this explains A.j.'s love for him, because A.j. has a type--so do I, of course). Which kind of makes Dee Terry. Which makes Lee Deadpool?
Or, bringing this a little closer to the core X-Book, Billy is the Piotr Rasputin of BSG, Dee is Kitty. And Lee is Pete Wisdom--because in this instance, Dad is Alisatire Stuart. And Mom is Alysdane (which, well, yeah. Except for the being military part. And not being quite so tall).
All of which kind of makes me want to write Kitty/Scott.
