    That is the kind of cable I use.

    Check the pdf manual for your devices (flashes, remotes) to know if a socket is for input (to fire the flash or the remote) or for output (to fire other flashes or remotes).

    The Profoto site shows the B1x as having a 3.5mm mini phone cable.

    Copal shutters, from many documentation sources, indicate a standard PC connection.

    The Hama cable you linked to has a 3.5mm mini phone on one end, and a PC on the other. This system should work.

    The main issue is you are going to need a lot more power to go from typical 35mm working apertures (5.6-8) to get to 4x5 working apertures (16-22) for equivalent depth of field. As long as you are two stops away from using your heads at full power you should be fine. I shoot portraits with 500w Bowens heads and it's easy to get up to full power if your shooting through a soft box.
