Henry,

Since you will have to use a longish time exposure, opening the shutters
just before your estimate of the instant that the lightening will strike,
surely exact synchronisation is not that important? Couldn't you stand in
between the cameras and release them one with each hand? (Preferably with
cable releases.)

Let us know how you get on.
