Nomad and Gadget

I'm doing a show at a festival next month and to save time when we get there I'm going to reprogram my normal show file to use their lighting rig, which I haven't been shown yet.

As they are using a Chamsys system I'll use my laptop with nomad to control the show, my question is about using the gadgets with the system. I have access to a Gadget 1 with one port and a Gadget 2 with 2 ports.

I know I can connect units together to make up to 4 universes I just wanted to check it is ok to combine different versions of the gadget as if they end up with 3 universes I need to use both the 1 and 2.
