4. Scaffold Matches
The risk here is inherent, as plummeting from a considerable height down to the canvas is no picnic. However, you could argue that Hell in a Cell and ladder matches (as well as whatever Shane McMahon's doing) already go the stuntman route, so why *not* erect that old scaffold?
In this era of cinematic wrestling, you could put production around it, filming the finish so that the inevitable descent is done with camera tricks. If you can minimize that risk, and you have a story worthy of the gimmick, then scaffold matches may as well see new life.
