Cannibalizing working C=128s is a stupid idea. Working 8502s are best to keep as repair material for machines breaking in the future.
WDC 6502s are not compatible, because (AFAIK) they are 65C02s. The so called illegal instructions of the original 6500 derivatives are not present and those also lack the integrated I/O port.
No PLA replacement will ever have even a snowball's chance in hell to be turned into a CPU replacement.
Unfortunately, your best chance is FPGA implementations for [7|8]501 and [7|8]360. It's a pity that nobody is willing to make them.
