Being able to "toggle" movement would be like changing the shutter speed on an analog camera, while the end result is purely aesthetic, making that change fundamentally alters the way in which you have to use the camera. Swapping out two seperate ways in which your character interacts with the game world would require two back end programming architectures to calculate a similar end result.
