It could be molded into a form based on tapping pressure points, but instead, stabbing with a lightsaber. There are martial arts based entirely around pressure points, and the way I see it, you could easily do the same with a lightsaber, although it wouldn't be very effective in a duel, as it would compare to an unnarmed monk trying to stun a swordsman with the tip of his fingers. Your character would likely need the natural ability of speed, plus decades of training and refinement before a showdown against a boneafied swordsman.
Having said that, I think you should just impliment it as a maneuver or combat device, not an entire form.
