Honestly I think most of them would. They aren't complicated stories or anything, in fact NXT's stories are fairly simplistic. For example: Baron Corbin and Bull Dempsey feuding over who is the true monster of NXT, it's a feud based on two guys who want to beat the shit out of each other. Neville/Zayn was basically the Cena/Bray feud from last year only told better. Owens/Zayn is probably the one that might not work on a mass scale due to its indie wrestling tie-ins, but even NXT found a way to tell that story in a pretty simple straight forward way.
NXT can totally work on a larger scale.
