#1. HHH

This is probably inevitable. HHH is indeed getting up there in years - but so is Punk. Still, there's potential to draw a lot of money from having these two guys feud against each other.
After Punk left WWE, he's made several remarks about the way HHH handled business in the company - and none of it was very complimentary. On the other hand, HHH's wife Stephanie McMahon has used every opportunity to take a shot at Punk, especially live on TV.

It's also worth remembering that they already had a feud in 2011 when Punk was a red hot commodity. HHH won the feud, and to this day, he's disliked by some wrestling fans for choosing to kill some of Punk's momentum. A lot of references can be made to the past if they were to butt heads onec again, and it's sure to feel realistic.
It's even worthy of a spot at WrestleMania - especially since that was the rumored match Punk was supposed to have at that very same event the year punk left WWE. However, there is no doubt that, this time, Punk should be the winner. A victory for HHH would render this pointless, and besides that, it is unlikely that Punk would agree to lose this match. The fans would probably not take well to it, either.
At the end of the day, this feud will get people to talk and needs to happen should Punk return.
