This is too easy, even without build. It's Trips/ The Glass Ceiling we're talking about...

Book the match as Jeritron stated, or even a clean match... I could see it playing out something like this:

First 15 or so minutes the match is clean as can be, and back and forth, nobody really getting the upper hand. Hunter is clearly getting upset by this point, as he's usually pretty dominate in the ring. He slowly starts using his underhanded tactics more and more. Every heelish act gains him a little bit more ground, but still Sheamus wont go down. HHH is pissed by this point, and causes Sheamus to take out the ref. A low blow later H takes him to ringside, and out comes the sledge. Hunter decimates with his hammer, then destroys ringside with what's left of the celtic warrior. Back to the ring as the ref is coming to, and it's the Pedigree followed by a quick pin.

(Assuming he calls Mania) Good ol' JR: HE KICKED OUT! HE KICKED OUT! HE KICKED OUT!

Trips goes nuts and goes after the ref, but Sheamus is up, staggering around just long enough to intervene with the cross. Ref counts the 3 for the upset victory. Sheamus gets his bearings and gets a little revenge for the beatdown before refs and security come out and break it up, escorting The Game to the back. The Celtic Warrior gets on the mic and announces that he knew that that was exactly what it would take to put HHH down at Mania.

Don't know how well this would work out in the PG era, but the key thing to remember here is it's the cerebral assassin we're talking about here. With his history, a turn could come at any time, and against anybody.
