I've located some small 28C64s. The advantage is that these can be programmed with the debug board while on the KIM board. It should look good as well because it will be tucked under the 6532. The registers are slightly different on the 6530 and 6532 but they should work the same if one ties the 6532s A4 a constant high. This looses half the 6532s 128 bytes of RAM but the 6530 only had 64 bytes anyway so nothing really lost. The only difference then is the interrupt. The 6532 has edge or level interrupt but few people wire up the interrupt. It isn't clear but I believe the 6530 is a level interrupt and that should be the reset level for the 6532. I'm looking at board maker options.

It is possible to have the 6532 and a eprom as a 6530 emulator. Allison
