Re: An idea that hasn't been done before
They haven't done the OP's idea exactly, but they have done it in triple threat matches where the biggest heel and the biggest face team up to take out one of the other guys in a heelish type of manner. I remember CM Punk and Cena suplexed Ryback through a table, was a pretty cool dynamic, I might add. In TNA, James Storm and Bobby Roode did a similar thing to AJ Styles in a triple threat match too.
Not keeping it real in the streets
