Honestly, that's one of the worst ideas I've ever read. Almost as stupid as Austin and Kurt Angle joining the alliance during the Invasion.
Outside of one of the originals actually switching sides, I don't think it's a bad idea actually. The New Breed would have to be 'losing the feud' though for Vince to go out of his way to claim that someone is switching. Build off miscommunications and whatnot on the originals side, and it could create some tension. Just make sure that no one actually switches. I mean, can you really see Dreamer, Sandman, Balls, RVD, or Sabu going corporate?
They need to bring back Foley so he can do the Unkle Eric promos again and I remember Mr. Monday Nite RVD going corporate back in 97 when he turned heel.
