That would become very complicated trying to define the difference between a stunt role and an acting appearance. For instance in images I posted today Franco Ukmar just stood in the street looking tough playing a henchman with no action involved, so for me that would be an acting role rather than stunt, but the leading actors all got hit in fights so those were effectively stunt roles.
If they are separated then I think it should just be the "Master of Arms", "Stunt coordinator" and other production credits that are kept separate, and if a stuntman who has one of these credits also appears in the film then it should be noted as "uncredited as actor" (unless he is also credited as an actor obviously).
