The idea of reusing the Two-Man Power Trip is tempting, but there is no one on the roster of WWE that could pull it off successfully, as was stated multiple times before. Triple H doesn't seem like he'll be getting many feuds going, with his injuries, and we all know the Deadman is in the same situation (also he's already in a "tag team"). So those are two huge main eventers out of the bag.
Randy Orton and John Cena were repeated multiple times -- though I'd like to see them in a tag team just because you know there will be issues between the two of them in working together, I just don't think they'd be able to pull of that "power trip" part of the deal. When Triple H and Steve Austin teamed up, they both had notable feuds with other tag teams, which the WWE is severely lacking at this point.
Basic point is that the Two-Man Power Trip is never going to reoccur, simply because of the fact the WWE is growing new Superstars and the Tag Team division is being given the blind eye for now. Until McMahon decides to create more stable and (decently) permanent tag teams, we're just going to go through the random team up process (i.e. ShowMiz, R-Truth and Morrison, etc), and sadly, I don't think we'll be getting anything solid for some time.
Besides, why recreate something that has already happened? If you just remake the Two-Man Power Trip, it won't have as much effect as the original. Don't rework something after the first time. Don't believe me? Look at the multiple remakes of the Montreal Screwjob that McMahon has been throwing out there. No one really cares for the remakes anymore.
