Back in the days of Vanguard - Sage of Heroes, there was a light fighter/healer class called the Disciple. They only used light armor and fought using bare hands, knucklers or claws. The cool thing was that when they fought and performed certain combos (a la Street Justice) they would trigger melee range heals as they fought.
They had a choice of following 1 of 3 different schools (like the forms from Staff Fighting) and depending on that choice it determined the secondary effect of your combos.
One was heals, another was armor/resistance buffs and the other was debuffs.
You had to select a School to follow and were locked into it.
It was such a fun class to play.
I wonder if something like that can be done.
