I was thinking if it would be a good idea having a Tag Team Money in the Bank match. 4 teams, one ladder, one contract and have it annually at Summerslam instead of having 2 at WM. This way fans don't have to wait one whole year for this kind of match. 2 a year and being different (one singles/one tag team) would contain the crowd.
It might inspire WWE to actually get a half decent tag team division together and push teams.
