I know, this is completely random. I wish I could say a match like Money in the Bank where multiple Superstars could perform, but it's highly unlikely due to the success of MitB being such a successful PPV in its own right.
I don't know how long Kofi & Truth will hold the title, but I did see them in a match when Raw came to LA back in February as part of the Raw Tour, more than two full months before they actually defeated Epico & Primo for the belt, so the WWE has been planning it for awhile.
Anyways, I always enjoyed the TLC matches, and the three-way matches back at WrestleMania 2000 & WM X-Seven where the Hardyz, the Dudleyz, and Edge & Christian put on impressive matches.
While no one is every likely to repeat those performances, the WWE has to put some life back into the tag team matches, and TLC is the perfect way of doing so.
So while I doubt Evan Bourne & Christian would ever become a team, it would be pretty awesome seeing them and Kofi in a TLC match due to their high-flying abilities and risky maneuvers. R-Truth would be no slouch, as I can see him going full force as well.
