All but one of the rotors seem to be basically a ring of 26 contact pads on each side, with arbitrary (but fixed) interconnections between the sides. (The reflector would only need a single-sided PCB, and jumper wires on the non-clad side.) You might need to bring one side out to a (smaller) ring on the other side and use jumper wires, I suspect it's not topologically possible without, though you could probably do that by sandwiching several PCBs together. Achieving good electrical connections between the rotors would be interesting. Might need a divider between the rotors to hold spring-loaded contacts to ride against the rotors, since you wouldn't have the (presumably) spring-loaded contact pins of the original. Or look at how (older) rotary switch contacts are made. I'd think it would be the mechanical stuff (including getting the contacts to the rotors to work well) that would be most challenging.
