Ooh, we have a hardcore championship? (Also I don't think we should have a royal rumble belt, but that's a match for a title shot at Bustermania, or maybe even the belt itself just like the real Royal Rumble. Also it shouldn't be called the Royal Rumble.)

And the way you described the Bustermania Championship makes it sounds like it's won via bracket tournament, like King of the Ring, or Cruiserweight Classic. I like that idea. I like me a tournament.
