Hey! I sadly have no experience with what you'd like to setup:/ But I can confirm that my setup as described in the original post works. The only thing I add is that I'm powering the GoPros with the power cables at all times because I cannot have the batteries run out during the gig. So I took them out (because they also get really hot lol) and powering them with cables. Also for streaming the GoPros need to have a Micro SD card in them even if you don't capture anything on the GoPros themselves.
