Commercial viability does not require mass production. THere have been many companies over the years who make low-volume bicycle drivetrain parts, although most have gone out of business or switched focus. If it takes ~3 hours in a machine shop to make your part, and people will pay $300 for it (which is not an unreasonable price for a fancy piece of bike equipment) then it could work.
