If he really hated Vince TNA would love to take him in a Heartbeat...even for a year contract.I'm guessing they would also pay for him nicely.Although he has stately publicly that he is not crazy about the octagon that they have.
As far as him not being able to wrestle.True, but with his nephews and niece in the WWE I'm betting it does make some type of on air character a possibly PLUS he does love acting and there is more of that(mostly bad) then ever before in the WWE.
Plus can you imagine a DX VS Hart dynasty feud? Like Legacy the dynasty have their number and no one can figure out why.....until....the curtain is pulled back....it seriously would blow the roof off the place if done properly and all parties involved were willing to do business.
