I think maybe the closest I've personally seen is some of the combat move options in the HERO system. I'd have to dig in my books & files (ergo not happining tonight because family) but I recall combat levels & optional move combos that could sort of maybe look like the basic adv/disad stuff. The "make a skill roll to activate your power" is there too, though not usually applied to martial arts moves.

Not talking about buying auto-fire on your punches for speedster characters. But there was an actual sheet of assorted moves (throws, trips, jump kicks, move by, move through, haymaker, etc.) anyone could use in combat and buying combat levels could improve how you did them. Point buy being point buy I suppose you could use them as the basis of actual powers.
