These modern "fixed-width" cranksets with their dearth of bb spindle-length options, has had me doing the asymmetric installation on many a modern bike for chainline considerations. And this bike with 126mm rear (as on my own Performance) does sort of beg for some chainline adjustability.
When the time comes to change my bike from 6400 cranks to compact cranks, I will first look long and hard for a 110mm crankset that will go straight onto the stock Klein spindle and have arms and chainrings fall right where they need to be. Thinking that one of the many different good old triples having removable granny-ring spacers (such as the Specialized triple, the Sugino AT triple or even the old MT60 Deore triple) will accomplish this.
BTW it's good to see that these frames appear to have decent chainring clearance relief at the driveside chainstay.
Never give up seems to be the lesson from your modernized Klein project.
You could always do a triplizer for a square taper double crankset. The Willow ones are about gone now. I think that company is out of business. I believe Specialities TA makes a triplizer for 130 BCD double cranks, and possibly IRD too. Or as you said, Specialized, Sugino AT or Deore (LX, XT) used cranksets that have been rescued. Knowing me I would want to polish a used crank, but I need to learn to just get things working properly so I can ride them right away and quit worrying about if it has a polished finish or not. Spa Cycles in England is a touring specific bike shop that sells a lot a triple cranks new, some at very good prices.
My Performance accepts 130 spaced wheels, so does the Quantum. I’m not sore if someone cold set these. I did not think oversized aluminum took very kindly to cold setting. But I see no ripples in the tubes, they are stout as can be. The long wheelbase Performance will be fun to build up since there is clearance for fenders and I have some handmade wooden ones I got from eBay when a shop was cleaning house.
