If you want the hub that has the chainline you want, is designed for SS/FG operation from the start and has the nutting/QR you want, consider Phil Wood. Don't see the perfect hub in their catalogue? Call or E-mail them. They aren't a distributor that has to work with a factory. They're a machine shop. It's the same labor to them to make your perfect hub and another typical one to put on the shelf.
When you talk to them, you get to talk to someone who really knows his stuff. He may well know a standard part they have in stock to do exactly what you want.
I contacted them at this time last year for a narrow BB with custom asymmetry to set up a unique "triple chainline" fix gear. Three entirely separate chainlines to use both sides of a flip-flop hub with a 2 cog "dingle" on one side and three chainrings up front. Each combination of chainring and cog adding up to roughly the same total so the hub always stayed inside a standard Campy horizontal dropout but the gear combinations are appropriate for true mountain ascents with 64 yo CP knees and really fun multi-thousand foot fix gear descents.
Since I was using a standard track hub, I needed to keep the chainrings as far inboard as possible. I designed the setup to have the 38 tooth inner ring just about brush the chainstay paint. Chainrings were spaced much narrower than standard since contact with adjacent rings didn't matter at all but chainline did. (1/8" chain.) I contacted Phil Wood with a request for a short axle with a given asymmetry. Figured it would be custom and was fully prepared to wait. Their rep came back and said they had on the shelf a symmetrical stock BB 2 mm different in length and my asymmetry was well within what could be adjusted to with the stock BB. It works really well! They were a pleasure to work with.
Another option here - stock Miche track hubs. Built to 120 track but with an axle long enough to get to 130. You just have to come up with spacers. One caution - most of the Miches don't use the standard lockring. It is a slightly larger ring. The limitaion is that you have to go to a "bell" lockring for the 13t cog as well as a 12t cog or the chain will ride up on the lockring. (Finding a 12t bell-shaped lockring with the Miche threading makes finding needles in haystacks look easy. You can have a machinist re-thread a standard lockring to the Miche threads but you may have to re-finance your house to have it done on the hardened steel.) I do have one Miche hub with the standard thread. It may be the "Primato" hub.
As you might have guessed, road fix gears is what I do. Setting bikes up to do on-the-road gear changes is a recent change for me but I have been riding road fix gears 40+ years. My true love.
