They would trade wins over the course of a few months, in the style of RVD/Jerry Lynn.
With all due respect, Whitey Ford, RVD won all his taped matches against Lynn except for their Hardcore Heaven 2000 encounter, in which Scotty Anton (Riggs from WCW) pushed Van Dam off the turnbuckle when he went for the 5-Star Frogsplash.
I believe Taz would beat Punk but show him respect for Punk's near falls.
