A few thoughts. For "sexy" appearance the Sugino Maxy arms may be more detrimental than the rings. It's a decent crank and definitely vintage but it isn't high-end or even middle-end. (I've had one on my UO-8 since the late 70's.) Sugino made quite a few models of 110BCD cranks which while not a pretty as a Campy NR are at least functional and semi-stylish.

I had never seen xxcycle so I went there. A giggle search which combines the terms sexy, rings, and xx-anything is likely to turn up some decidedly non-bike websites. No, I did not try that!

FWIW, my solutions to the low-gear requirement have usually been with a compact double crank, usually with 34T small ring, paired to a conventional 14-28 FW. Just about any long-cage RD can handle it. Short-cage RD's may not. For example on the Grandis I just built up I tried a Campy NR. Though it could handle the chain take-up and the 28T sprocket, it couldn't do both at the same time. Which is to say, it could do the 28T sprocket with the big ring but the big ring/28T combination moved the guide pulley too high. A Soma long-cage on the RD fixed that.

For the Masi I wanted to keep the Campy 144BCD crank. That meant using a 36T sprocket, which meant using a long-cage on the NR RD. Careful positioning and a larger guide pulley made it shift well enough even though it isn't up to Cyclone GT standards.

So there are solutions but you have to take a holistic approach.
