As previously stated in this thread, Edge would benefit the most from coming to Raw, Triple H still has some unfinished business on Smackdown, it would be the same as ending the Legacy premature as someone else said.
Kayfabe wise, they acknowledge that Triple H married Stephanie but got divorced, it was the main story of WM18, unless creative really thinks we can't remember as far back as the Royal Rumble, I seriously don't think they would risk putting Triple H on Raw, especially as no-one, not even him would benefit from it. It would just put me and others off watching Wrestlemania!
