There was for like a month in 2005 when Cena as WWE Champ was drafted to Raw, a month later the World Champ Batista was drafted to Smackdown.
They shouldnt merge the midcard titles, they tried that before and it sucked. They need to keep one each on both shows, I can see the IC title going to Raw in the next few weeks with Sheamus taking the US title to Smackdown. Probably have Kofi beat Barrett for the IC belt.
