I think you could probably just parallel connect the quartz clock terminals on the cameras.

As long as your leads didn't have too much capacitance, it ought to just work.

The phase shifting you can do in software by (for example) restarting the camera hundreds of times till by chance it starts a frame with the phase offset you want, and then just run on from there.

Won't two clocks interfere with each other?

As long as they're tuned close-ish to eachother, they will synchronize and oscillate in lockstep.

I'm talking the actual quartz crystal here, not the output of some digital clocking chip (which you're right, wouldn't work).
