A lot of play by post games did similar. At a basic level, each character could have ratings in each of those maneuvers (or whatever you chose). When there's an exchange between characters, each one picks a maneuver secretly and both are revealed - the winner gets an effect equivalent to their rating.
This also creates some more interest, as the big bruiser that does attack will need to be defended against (assuming defend beats attack)... but.... since they KNOW this they also would want to do some feinting on occasion to beat the obvious counter to their strong move.
