I don't think you will find a lot of people who have done it but I have seen a couple.  As far as I know the ones who did it seemed ok with it.  The first one i saw was ages ago down in MD and his rig was a little Mickey Mouse.  He put a small gas motor behind the unit and used a belt drive to turn the paddles.  I saw one in Ohio also ages ago that did it.  I don't remember much about his unit.  It would probably make more sense to trade the XPW in on a T series or Hybrid.
