Try placing poles around a circle. I've never personally done this, but I've heard it works for ex-racehorses that won't pick up the RIGHT lead (they're only run in one direction-the left). If you put them just a canter stride apart, it forces him to bend around and use his legs and haunches correctly for the lead you want.
Good luck, sounds like a toughie!
