7. Triple H
Pros: A historical rehash of their ultra-intense Attitude Era feud would certainly be received well by fans of both Austin and Triple H. Just as last 'Mania's Reigns vs Lesnar main event injected a surprising element of grisly violence into the largely clean modern era, this match would hark nicely back to a time when the hatred between wrestlers seemed far more real and palpable. Cons: Triple H looks to be on course for a mixed-tag match alongside Stephanie which, if indeed contested against The Rock and Ronda Rousey, could break serious ground in the WWE's quest for greater mainstream appeal. That's one cash cow the company would not be willing to sacrifice for a match we've seen many times before, even if the two share an undeniable chemistry.
