relays to connect only the selected Beverage to the ground rod

I've done this for 31 years from 3 different locations with no problems.

I agree. I've done this since installing my first set of 7
Beverages in 1985 arranged like wheel spokes and have never noticed
crosstalk problems. I even sometimes switched two in parallel to
listen in two directions simultaneously in contests (NE and W when I was
in Colorado). Now I prefer diversity (Beverages on one RX and an RX 4SQ
on the other RX) for contests.
