If the controls are solely on the chair, you might be able to mount a driver's side chair to the passenger side.

1. you'll have to adjust the chair rail
2. the side airbag will be on the wrong side
3. the controls will be on the wrong side

I'm guessing you could take the entire lower portion of the driver's side chair and mate it with the passenger's side back support to retain the SRS. Then you'd have to switch the chair control's side ... but then the controls would be reversed.
