Supersonic Trio!

Hi everyone,
In my intend to rackmount my equipment, I'd like to join G-System and Nova Drive for the electric parts, and the G-Major 2 (not bought yet) for the acoustic parts. Everything controlled via MIDI.
My Strato's got a piezoelectric bridge and the 3SSS. 3SSS goes to the electric and the piezo to the acoustics.
G-System is the Master Control for everything. But! If I connect the Nova Drive via MIDI to the G-System I can't connect the G-Major 2 via MIDI! Is there any possibility to join the three elements and making them rule the way I want?
Tip: Nova Drive works with the MIDI Channel 2, and G-System only works with one MIDI Channel, it should be #2. If I do that, I should put Channel #2 to the G Major. But then, I'll change things in the Nova Drive. A big drama! Could the G-system work with two different MIDI Channels? One for the Nova Drive, and an other channel for another device, in miy case G-Major 2?
Thanks a lot!
Best regards!
