Eh, that wouldn't be as awesome, I don't think. It would be an interesting game though, to have Zelda a main character, and have her be able to transform back and forth between Shiek and herself. It could be done in the same way Paper Mario is, in that you play through as Link, and then in between dungeons, you could have something to do as Zelda. That would have been awesome for OoT, to see how Sheik seemed to be EVERYWHERE at once....
