Is your "multiplexed switching" another way of referring to a phantom

Seems like an invitation to problems if anything happens to the interface
section.
Suggestion - Use the other two connectors on the 4-pin Jones Plug to
interface the TR control link thereby keeping the DC away from the RF
connections.

I have been using this scheme for many years... and have other
customers also running the multiplexed DC signal. I have never
experienced... or heard of any issues with that arrangement from my
customers. It works just fine and eliminates having to run additional
wiring from the transmitter to amp for people that aren't satisfied
with just using the COR switching.
