I run amps for 2m and 70cm (both GG triodes) off a common supply.  Like 
the original poster (Dino) is proposing, mine is set up so that only one 
amp can be keyed at any one time.  Mine uses common anode and grid 
current metering shunts (plus protection diodes) mounted in the PS.  So 
the (remote) meters read for whichever band I'm currently Tx'ing on.
