#4 Tag MITB matches would be within the Idiom for the Money in the Bank pay per view
Years ago, TNA -- when it was still called that -- came up with the Lockdown PPV. EVERY match at that event was contested in a steel cage, which was just as awesome as it sounded.
With a Money in the Bank themed pay per view, the WWE could accomplish the same thing. There could be two additional MITB contests to flesh out the pay per view and keep the ladder theme going.
