Switching controls

Hey everyone, I have a friend who is actively looking for a Spyder RS to purchase. He has limited use of his left arm and no use of his left hand. He's ridden a Spyder at parking lot speeds and can place his left hand on the bar to help. The question is, has anyone heard of switching the gear shift on an RS to the right side? It seems like it would be a simple matter of switching the gear box with the starter assembly on the right, with worse case scenario being that the shifter is upside down.... Thanks for any input.
