If Vince would be willing to make fun of himself, what they should do is have Vince's guy lose the match. Vince tries to run away, but the guy with Trump stops Vince, brings him into the ring. They have Trump in the ring ready to cut Vince's hair off, and when he goes to grab Vince's hair, he just pulls it right off, a hairpiece. Then Trump goes on to shave what little hair is actually on Vince's head.
It would be simple to do (just shave parts of it off before the match, but make sure to get a piece that looks just like his hair now), and to me would be a pretty funny moment. But, yeah, I highly doubt Vince would do that.
