If the motor is a synchronous motor reversing the polarity will not work. The motor will still turn in the same direction.
If the motor is synchronous there is a solution - providing you can find the room and a mounting solution - by just adding a small gear between the motor gear and the worm gear. The size does not matter. Just the teeth need to mesh properly. The additional gear will cause the mount to track in the reverse direction at the original speed. I did this to an old Cave Astrola mount and it worked perfectly. However, these mounts are usually designed for 60hz current. They run at 50hz but too slowly so you then need to build up a frequency generator and that is a can of worms to say the least.
