I would suggest that you equip each radio with a 2 position coax switch and a 100 watt dummy load. Switch the radio to the dummy load when it is not being operated and to an antenna when it is used. That is the fail-safe situation if only one radio is to be used at a time.
OTOH, you mentioned only two bands - 40 meters and 70cm. If operation is confined to those two bands, they may co-exist just fine and even allow simultaneous operation if both transmitters are sufficiently clean. If there are problems, a 30 MHz low pass filter in the HF antenna line(s) should cure it, and a High Pass Filter in the VHF/UHF antenna line(s) will even allow simultaneous operation with no problem.
If you have more than those two transmitters, a set of good bandpass filters for the HF bands would be in order.
