This is an idea that could be cool - I'm not talking about unifying the WWE Title and World Heavyweight Championships (although I'm always all for that) but rather someone winning both world titles and holding them on both of his shoulders at the same time. Imagine that for a few months or however long this person held both belts, they went around proclaiming to be the ultimate world champion of the company.
The idea could work because there isn't really a brand extension anymore. Someone might try to point out a flaw in the idea by saying that if someone had both belts and they weren't unified, wouldn't they have to defend them both in separate matches? My answer to that is that this person could either simply defend them both as if they were one world title, with the idea that the person who won them acquires both belts, or since that idea is very close to it being just one unified championship, maybe they get their way of having to defend them both every month by the 30 day rule. The original rule stated that you have to defend your title every 30 days. As long as they were defending at least one of the belts every 30 days, they could still get by on it.
Someone might try to point out another flaw by pointing out that it screws up the house show situation because both house shows circuits aren't being headlined by a different world champion. Really? The Rock is the WWE Champion and isn't appearing at house shows as we speak (not a negative criticism, just pointing out facts.) I think the house shows could survive for however long this guy held both titles. Besides, does anyone really believe that a world title is gonna change hands at a house show anyway? When's the last time ANY title switched hands at a house show? Jeff Jarrett losing to Edge in 1999? (And he won it back the next night at Fully Loaded 1999.) I think house show business does well because of the guys involved and the WWE brand name, so house shows wouldn't be affected at all.
Here's another idea - this same person loses both of them in the same way that Kurt Angle lost the IC and European Championships at Wrestlemania 16 (I don't say Wrestlemania 2000, it sounds so lame and generic.) For those who don't remember, he wore both belts and had to defend them against Chris Jericho and Chris Benoit in a triple threat match that contained two different falls/matches - the first fall was for the IC Title and the second was for the European title. In the first fall, Benoit pinned Jericho to win the IC Title and Jericho pinned Benoit to win the European Title in the second fall. Do the same with the world champion - he has to defend them both in a triple threat match against two opponents and there are two different falls, one for each belt. The champ walks away with neither belt, despite not being pinned or forced into submission in either fall.
I think it's a good idea to try on someone who has just made their way into the main event. Take Ziggler for example. If he were to qualify to compete for the WWE Title (by winning a tournament or battle royal or whatever) and won the belt but also used his briefcase to win the WHC that same night. And then after carrying both belts for awhile, he lost them both without taking the pin himself.
