I thought about you mentioning tire rub.

I guess I'm thinking short of frame modification to allow alignment of both sprokets and no chain rub on tire, could you find if anyone else had this problem. I think one way out could be having the rear sproket shimmed outward as long as it does not hit the rear fork left side. This would make it so you can have more space between the tire and the chain and also get both sprokets with the chain straight.

I did not see pictures showing exactly how the rear drive sproket looks where it attaches and how it passes through the left side the rear spokes. I guess it is a clamp on to the hub and some spacers to go between the spokes. Longer spacers if possible is what I was mentioning above, adjust shim ect.
