If you could get your hands on a used Dectane or something and attempt to change it to RHD, it would be awesome. However, that could be like the "last" thing you do as retrofitting projector lenses in the stock head light units is more important and beneficial, to be honest with you. Not only will you design it the way you want and put anything you want inside, but also you could make a small home-business out of it by retrofitting lenses for others. You'll need to do it at least twice or three times, though, and perfect it before you actually start doing it for others because as you may know, people may start blaming and pointing fingers like I am doing at the guy who did them for me right now.
