I think this would add a lot to an already cool bike, and is very 60's show car-ish. what is the clearance problem? could you not just create a mirror image of the existing drivetrain? The left side would probably just be a dummy...if it is a frame clearance issue, I might add that it isn't that hard to dimple a frame for chainring or chain clearance. I have done it to a touring frame to fit a triple in place of a double. All it takes is something with a blunt rounded edge to use as a punch, and also use a lot of patience (don't use a huge hammer), and just work that dimple in there.
