MTVMANN, you mentioned Idina singing the part, I agree. Singing only. I suggested her playing the part to a friend of mine and he brought up a great point she's "too Jewish." And then it hit me "Duh, Jaime wants a girl who's not Jewish."
She gets thrown out a lot for playing Elphaba, but I think Caren Lyn Manuel would be a nice Cathy. And I'm also game for Gavin Creel as Jaime.
