I could see a well-motivated hobbyist or group of hobbyists doing the design for fun, or to make a point. People do similarly ambitious things all the time.
Behringer has impressive scale, but honestly I think for PCB manufacture and assembly, JLCPCB probably has them beat -- and any random hobbyist has access to JLCPCB.
The cost of Maths and Rampage has more to do with having to earn enough to pay all their employees and make a decent profit that the actual marginal cost of manufacturing one more module. Maths is very popular, but it's still a fairly low-volume market.
I think one thing it would be hard to compete with Behringer on is enclosures. But maybe that doesn't matter; a Neutron/Proton clone wouldn't necessarily need one if it's a Eurorack module.
