I think it can be done BUT it would require the same setup on each camera., I would hate to have to set it all up
Stage one
you would have to have the same camera on each with the same settings
Stage Two
However you would need a transmitter and the same receivers on each camera that the transmitter would trigger the cameras
Stage three
You would need something like Pixel King transmitter as the transmitters have a by pass connection so you can fit a flashgun on top
stage 4
same flashgun for equal power on same setting
so you would end up with something like this on each camera. One transmitter as the master and the rest acting as slaves. You would need all on the cameras as shown so they react to the camera trigger if you wanted them all camera mounted
why pixel king transmitters?
Stage 5
using them you can also trigger remote flashguns ,not only on top of a cameras, using Pixel king receivers also you can alter the flashguns to suit depending which channels you use
As I said at the beginning it would be a nightmare to set it all up let alone all the AA/AAA batteries you would need
Phil mentions using GODOX buit as far as I am aware GODOX doesn't allow a flashgun to be mounted on top of a camera as in the photo I posted Pixel King does
You would not be able to make adjustments remotely however you would have to alter flash trigger and or the flash gun .
Lets take it a stage further as to cost
say cameras+ £ 1500 x3 = £3450
decent flashgun £250x3 = £ 750
flash trigger/ receiver x3 = £300
Camera trigger/reseiver =£300
Batteries AA enelope pro x 50 =£100
batteriesAAA x20 = £30
Memory cards =£100
Battery charger decent one =£60
Tripods x3 cheap =£300
Tripod heads x3 =£400
total =£5000+ if you lucky More like £6000 upwardsand that is without anything to carry that lot in
And that is not including extra flash guns etc just to take a couple of photos, presuming you already have all the camera lenses for say 3 cameras or you can add on a few more thousands of pounds and you would be lucky to get away with under £10,000
