I don't really know, and that's a good thing.
On one hand, James Storm really really needs to turn heel, he needs a character shakeup like crazy. Then again, Storm's better as a face. Storm's one of TNA's more well-established guys, so to turn on a bit player like Gunner who barely seems like a face seems really awkward. Would that work well?
Or they could turn Gunner, who is probably more suited as a heel anyway... but that would leave Storm as a stale babyface...
Either way, they really just need to make these two interesting.
