That sort of thing is what diodes should fix.  Just put a diode in series
with each one then connect the sides not connected to the camera together
and to the switch.  If a diode is backwards then that camera won't fire, so
turn it around (easier than trying to explain diode anode/cathodes and such).

Chances are, the diode drop won't hurt things, although one could use
schottkey (or germanium for that matter) ones with lower drop.  But it's
unlikely, I suspect, for that to matter.
