Here's an idea: Steel cage on a pole match
A pole is center of the ring, with the top leading to a circular hole of what is essentially an upside-down HIAC which is suspended from the roof.
The match begins in the ring, and the opponents are to climb the pole to enter the cage, then climb out of the cage from the top and land on the ground first to win. There are safety nets surrounding the outer ring to land onto. Almost looks like a Kami's lookout but with a cage instead.
