Quite simply, no.
I don't think the Briscoes are as adaptable to the main stream as say Bryan Danielson, CM Punk or Nigel McGuinnes. They are very stiff and prone to the occasionaly severe botch (Mark). As much as I'd love to see them there I also dont think the WWE would tag two guys that are so obviously a tag team with little singles potential seriously as the WWE doesnt value their tag teams that match. I would love to see them there and maybe the WWE will try something new, but the usual WWE route I dont see hiring them.
