If you are talking HF, legal limit, many open frame relays work just 
fine. I run SO2R with a commercial 6 pack.  6 antennas and two rigs.
I only run one station at a time so high isolation isn't a problem. With 
DPDT relays on SO2R the second contacts serve as a lockout. with 5 to 6 
rigs/stations you are probably looking at a single logic setup fed by 
switches at each station.  Perhaps some one else has a better idea.
