Got it all put together. I still had the bars/stem/levers all taped up from the Orange Nano that I previously owned and sold, so I re-used those parts. Found some sweet old Sugino 144bcd cranks at the co-op, currently running 54/42 with a 12-28 XTR 8 speed cassette.
The fenders are Velo-Orange that I re-rolled, left them long for super-full-coverage and laughs, but have since trimmed to more reasonable length. Pics of fender re-radiusing here:

The tires are 20x1.75 and clearances are very, very tight. I will probably need to switch to the 20x1.6 size at some point but we'll see how these too. The fender gaps are correct and get slightly more open at the front so gravel and leaves do get pulled through but it's still pretty close.
The front rack is some weird old Cannondale rack that I cut down and bent the stays to fit, with a "wire letter tray" from Office Depot zip-tied on. It works quite well but is not optimal. Based on LOTS of research and measurements I believe the Racktime Topit front rack will fit well so I might try that at some point. The other option is the Civia Pizzeria rack, but I find the platform to be too big for this small bike.
Not sure how deep I want to go into this thing, but I also picked up a 32 hole dyno hub meant for small-wheeled bikes so maybe at some point I will rebuild the front wheel to dyno power.
Anyhows it's lots of fun to ride and that's what matters for now.
