If there are worries about connecting the relay control circuits
together, one can put a diode in series with each one (anode toward the
amplifier). Connect the cathodes together and ground them to key the
amplifiers.

I think this only works if one of the amps is off. I you want to use both
amps simultaneously to obtain 1.5KW, there may be an issue with the two
relay voltage sources.

going to a kxpa100, the other going to an external amp, in my case a
kpa1500.
Will this work?
Sure, as long as both amps use the same logic for keying. I've done it
for years with a K3, switching between a KPA500 and Ten Tec Titan, using
relays to switch inputs and outputs.
