This was my first idea, too. Altering the actual combat stance would require changing attack animations, too (even though I’m not exactly fond of the standard combat stance either).
They usually use Mocap for animations (don’t have to, but it helps). Which gives me a sort of chuckle when I hear a request about twirling daggers in their fingers. Someone at the office is gonna have to learn how to do that to get it mocap’d if they go that route.
