heyas; it depends on what you want him to wear. if you replace the feet with props, there will be a seam there; whenever you beend the foot (now a flipper), it won't be welded to the ankle. hmmmm... you could weld the flipper objects onto the figure for a new base figure, but any time you weld seams, you risk screwing up the morphs for any/all the body parts. i wonder if you could parent the flipper to the foot with inherit bends on, then replace the foot with the flipper. okay, the easiest thing to do would be to build the flippers over the ankle and foot, parent them to the foot with inherit bends turned on, then make the foot and toes of the figure invisible. i think.
