I'm late to this thread - Google brought me here because I want to put an ultratorque chainset on my brommie. I'm not sure I'll be able to do it quite as elegantly as you, but wanted to check whether there had been any issues with the chainline / other dimensions with a 52t ring on the inside.
Have you tried folding the rear triangle? I'm currently running a vintage DuraAce setup which required minor surgery (machining off the inner studs and fitting the ring on the outside) to avoid fouling the rear triangle during folding (fitted fine except for that).
This is a fantastic build.
