Mixing Blue and Black Widgets with Hog4PC?

Quick question--I'm spec'ing a system right now with a single DMX universe. Currently I'm opting for a blue Hog3PC widget for simple affordability, but there's the question of future expansion to additional universes. Would I be able to have the blue widget in operation alongside one or more black Hog4PC widgets without any issues?

Computer OS is going to be Win 8.1, if that matters at all.
