Nah. Even using the limited "WWE Main Event Style", Heidenreich still can't work. Can't bump for shit, horrible punches, just plain awful. He's barely passable as a midcard act, and that's only because the "MAH FRIEND!" and LOD schtick got him over.

Add:
-he often looks awkward in the ring
-he's not very attractive
It's a good bet the WWE knows his limitations, because they're quite obvious. They may give him a shot, which will no doubt bomb, but to say he's a "future long term ME'er" is ridiculous. Being a tag team champ in a fledgling division, and doing the "MAH FRIEND" schtick, is hardly what I'd call being pushed.
