That would be easy, but not cheap. It would be a lot cheaper to just replace the few bad parts on existing boards. Most modern electronic components have life spans in the hundreds of years if taken proper care of. The exceptions are potentiometers, switches, motors, or anything else with moving parts. Also, electrolytic capacitors and battery compartments tend to fail either due to fluid leakage or fluid drying out. Building whole new boards on a non-industrial scale would be very time consuming and expensive. So there's little motivation to make a whole bunch of drop-in replacements.
I've repaired hundreds, if not thousands of electronic boards in my life (many inside cameras). The stuff made around the turn of the last century (late '90's early 2000's) can be more difficult to work with due to their use of SMD parts. But even those aren't too bad if you have the proper tools, patience, know how, some steady hands, and a schematic. Most electronic components used in cameras can easily be replaced for pennies. Even the extinct components will most likely have a modern day equivalent that's readily available on the internet (Though some will have proprietary IC's that can't be sourced except from the OEM. But IC's rarely ever go bad unless there was a catastrophic failure elsewhere in the circuit). The boards themselves can be remade on the cheap (you literally expose and develop them like a photograph).
The only thing that keeps people from routinely repairing these old boards is they take a fair bit of knowledge to understand, and most people who know enough about them to work on them, don't want to waste their time working on them. There's not much money in camera repair, so there's not much incentive for an electrical engineer to go into that field when they can make multiples more money working for a large company. And most non electrical engineers don't want to invest the years it takes to learn this stuff. So you have the people with the knowledge but no motivation, and the people with the motivation and no knowledge.
Very curious, where did you obtain this knowledge as to how to fix such things?
