Oh, I have a balls out alternate theory where he takes up Mogo's place, taking charge of sending out the rings, except that he takes the Blue Lantern approach and goes to each possible Lantern separately. He sits down with them and talks with them and once he feels they're a fit, he offers them the ring.

I'm all about Kyle going blue as well, but I do wonder how they'll make it work if he can super power the others for anything.
