I agree Vince wouldn't allow it on the main roster.
However I do think there is a POSSIBILITY he would allow it on NXT. I think WWE would be less protective of that as it's just a developmental. Elite invades, feuds with both heels and faces, with the climax being the 3 man war cames. Elite vs Undisputed Era vs face NXT team.
Vince allowed Jushin Liger to show up at one taker over and cleanly beat an NXT guy, so I think he's less brand protective in NXT. Or perhaps Triple H is less brand protective and Vince just lets him do whatever down there.
