Serial and Ethernet Gateway on 1 Vera - or how to move gateway to new controller

Asking here first as this is more a Vera specific issue perhaps than Mysensors…

I have a Vera Lite (my test box) talking to a v2 Ethernet Gateway. It’s currently getting data from 3 v2 Power monitors. I have a Vera Edge, talking to a v1.5 USB Gateway. It’s currently talking with a v1.5 distance meter.

Is it possible to have the Edge talk to both gateways, if I add another instance of the Arduino plugin?

If it’s not, anyone got some guidelines on how to move every node to the USB gateway (if I upgrade it to v2)? USB has proven more reliable in restarting without intervention after power failures.
