It would be a fun project to reverse engineer.
Values for the resistors and caps should be pretty straightforward. It's the specs for the transistors that might be more difficult.
Go for it and see what happens. If you post as you go, people can colloborate with whatever they can contribute.
As far as producing, also think about repairing. If you can take them apart that neatly, if the parts can be sourced, just replace what's needed. Nacho was hamstrung in part because of his location made it that much more difficult to find the switching transistor.
There's a cutaway photo here but its black and white. Not really good enough to use for identifying each component.

ps It's possible the Hi-Rev 7500 version has assembled in US. I cant recall if anyone has cut one of those open.
