If you put 3 mm or so of spacers on the drive side flange of the bottom bracket, that'll even out the crank arms. And it should work so long as you have enough thread engagement and the NDS cup doesn't have a flange. Where would it put your chainline?
<EDIT> If your current bottom bracket's NDS cup does have a flange, you can replace it with a flangeless model like a
Tange LN-3922 or pick up a flangeless cup like a
UN54 cup or a
Problem Solvers UP-CUP to work with your UN55.

As far as I'm aware, there is no "correct" cartridge bottom bracket manufactured for it. The Maxy used an asymmetric bottom bracket spindle in a size that isn't made in cartridge form. I've got a bike with a Sugino Maxy crankset, fitted to a 3S spindle. It's 121.5 mm long: 32 mm on the non-drive side, 52 between the races, and 37.5 on the drive side.
