I think you'll find that using a second "duplexer" (cross-band coupler) on
the input to the amps will be cheaper than buying a high-quality coaxial
relay to switch between the two. Then you don't have to switch anything.

As long as the switch or cross-band coupler affords sufficient isolation to
keep the "wrong" amplifier from switching into transmit mode, it shouldn't
matter, unless you're concerned about battery drain.
