You may want to check out the products from TopTen. They are a little pricey, but they are what are used by many of the Multi-Multi contest stations to share six antennas with 6 high power operator stations. I just purchased one of their A/B switches to switch a single antenna between my K2 and Pro III. It provides 80 db isolation and uses interlocked relays to avoid the possibility of a relay failure allowing power to allow transmitter power to flow back into the rig not being used.
If you look at the application note one their site, it shows a setup very similar to what you describe.
