As my Mama used to say "If you got it, flaunt it".
The loops may give you some real estate for something fun/cool/etc. You probably dont want anything to district from the engineering that went in to building the shaft drive, but on the left side of the frame you may be able to come up with a cool bracket/dropout/panel that holds a pointed rear light, license plate, whatever. That may "hide" some area of the left side loop allowing people to focus on the the shaft side.
I'm probably not explaining it very well...........fantastic build/vision....
