I'm looking for an HF antenna switch matrix (or suitable combination of off the shelf widgets) that does the following... (this is all pretty standard in the audio/video switcher business)

4-8 antenna ports
4-8 radio ports

remote control interface that lets any radio select any antenna that's not currently selected by someone else.

Handles 1kW (doesn't need to hot switch)

grounds unselected antenna ports

Obviously a full crossbar type arrangement could do this.
So could a collection of standard 1 in, N out switches along with a pile of T adapters and jumpers.
And a microcontroller to select which relays, etc.

An expandable design would be nice (i.e. you could have 4 radios selecting from among 4 antennas, and then add "switch/patch bays")

Push buttons to select antennas (with feedback) and/or network controllable would be nice.

Any and all suggestions solicited.
