Some more for you bro.

Shovel punch
Teep kicks (to the front of the thigh or shin)
Spinning back elbows

Plus bro this would be very fucking cool cause its old school boxing jab jab straight KO like hearns vs duran.

Rolling knee bar.
Bulldog choke aka headlock.
Spinning back king to the stomach like the one gsp throws.
As a foul you could have hammer fists to the back of the head then ref stands them up, or idk if you can win by DQ these days.
