What if Chris Pine voiced Star/Star Boy?

Don't worry, I still think Chris Pine makes a very impressive Disney Villain as King Magnifico.   But I just couldn't help, but wonder lately: What if Chris Pine was the voice of Star/Star Boy instead?   Then he would use Jack's voice from "Rise of the Guardians", Star would be Asha's romantic interest and then, the song "At All Costs" would be a love song between the two.
