Seems like a Battlestar - Big Bang meeting would be inevitable!

I won't speak for the entire BSG crew here and now, but on a personal level I'm fine with any internal freaking out meeting Kara Thrace could lead to. Actual in-your-face canon-puncturing would be a different story because Kara may not respond well to the idea of her life being a work of fiction. So if Sheldon and Starbuck are going to meet it should probably happen when he's less likely to blurt out something about the show.
