I think getting reproduction boards made for some vintage TVs, that had issues with lifting traces, would not be a bad idea, or even tube radios with the same issue. Sylvania radios, and apparently TVs as well, had rather fragile traces that would sometimes be delaminating from the PC board well away from sources of heat, same with some early transistor radios. you can get small runs of P.C boards made to spec, even on phenolic board, and the beauty of it all is that that many service manuals had full size printouts of the traces, and graphics, on the original  boards, so you could get those reproduced. I think that the idea behind using modular chassis, with plug in P.C modules, had a lot to do with turn arounds in servicing, unplug the defective module, replace it with a new or rebuilt one, and send the old one to a rebuilder, in theory a good idea, in practice maybe not?
