Championship Gauntlet - Every wrestler that has a title is on the same team (ie, right now, you'd have Randy Orton as the team leader, Edge, Chavo, Jericho, MVP, John Morrison, Miz, Cody Rhodes, and Hardcore Holly as one team) versus every other person in the WWE. If at any time, any of the champions get pinned by or submit to anybody that does not have a title, they automatically lose that title to that person, and that wrestler picks up where they left off. This is an elimination contest, much like Survivor Series, except the champions team never loses a member, they just get replaced. For instance, say you started out with the team of the 9 champions against the first 9 competitors (let's just say, HBK, HHH, Cena, Undertaker, Umaga, CM Punk, Jeff Hardy, Kane, and Kennedy)...now, Kennedy pins Cody Rhodes. Suddenly, Kennedy is one half of the tag team champions with Hardcore Holly, and someone else (let's just say Shannon Moore) is called up next to replace Kennedy's spot. Kennedy replaces Rhodes. Rhodes is out of the match. Now, if Moore pins Kennedy, he is now half of the tag team champions with Holly, but if Moore is pinned by, say, Edge, then he's eliminated. This gives you the opportunity to switch titles multiple times during a match as well as have your own teammates screw you over. Morrison could force The Miz to drop his half of the championship to someone he'd rather have as a partner. Orton can screw Jericho out of his IC title and give it to a friend of his. Once everybody has been eliminated out of the challengers bucket, those who were able to successfully defend their titles (even if they just won the belt on the final pinfall of the match) walk out as the champions. If you're a former champ and you were pinned, you're not thrown into the list of challengers, because then the match would never end lol. The killer with this match is that it would have to take up the entire ppv or be spread out in a team tournament fashion over a few weeks. And, naturally, the women's title couldn't be involved, as you can't have the men pinning the women and so forth.
Note: A byproduct of this could happen, instead. At Vengeance: Night of Champions, where every belt is defended, they could do it so every title defense is a gauntlet in itself. For instance, Rhodes/Holly and Morrison/Miz defend their tag team titles against every tag team that wants to enter. Everyone has the opportunity to sign up to challenge Jericho or MVP for their midcard titles (so say, Kendrick and London want to be tag team champions, and they want to defeat Holly and Rhodes for theirs, they sign up for that one, and Festus wants to beat MVP for the US title, he signs up for that, etc). Naturally, you'd space it out so it makes sense. You wouldn't want Super Crazy challenging for the WWE title as he'd have no shot, but he could sign up for a tag title with someone like Funaki to spread out the match a little. That way, all of the champions prove whether or not they seriously deserve to be at the top of the mountain...that they're truly better than the rest of their competitors.
