Response Mk2 Gateway with Element

We are looking to upgrade our old Net2 Node to a Response Mk2 Gateway, running off an Element console. We want to be able to pull 4 universes of DMX, but is this even possible with the Element that only has 2 physical DMX outputs? If this is possible, my next question is if the existing wiring used for the Net2 will work with the Response Mk2.
