If you went with a hub mounted 3 step pully like the originals had then if made from iron or steel you could hollow out an eccentric hole at the back of the pulley which would help with balance. With a bit of cunning the modified hub could be made from a mix of aluminium on one side and steel on the other to add more hidden counter balance.
