Title unification matches would make for some good Wrestlemania matches. The US and Intercontinental should be the first (with whatever title is left being called the Intercontinental, of course). Then I would say unify the IC with the World heavyweight. And call it the Intercontinental title then too. Then maybe bring back a low-card title.
So basically go back to how things were in 1999 minus the hardcore title.
