Yeah, the more I think about it, the more I want there to be two Money in the Bank Ladder Matches.
At WrestleMania:
Edge vs. CM Punk vs. King Booker vs. Jeff Hardy vs. Mr. Kennedy vs. Randy Orton
At Backlash:
Rob Van Dam vs. Johnny Nitro vs. Kane vs. Shelton Benjamin vs. Matt Hardy vs. Chris Benoit
How badass would that be? Edge wins at WrestleMania, cashes it in and ends The Undertaker's 15-0 winning streak after he beats Batista. So Edge is now on SmackDown! as its World Heavyweight Champion. Vince McMahon decides to hold another one, just so there is a Money in the Bank holder past WrestleMania, and he decides to let the losers of the qualifying matches enter.
I'd actually give the win at Backlash to Chris Benoit (who would lose the United States Championship to MVP in a Fatal Fourway Match at WrestleMania also involving Matt Hardy and Finlay). Edge and Chris Benoit then tease when they are going to have the match, but when they ultimately do, Chris Benoit wins his second World Heavyweight Championship.
