USB DMX Widget - HOG3

Can I Use a USB DMX Widget as a DMX output for a HOG3 Console?

I need a single DMX output on FOH on a tour, and using a DP8K for just one DMX universe seems unnecessary.
I use fiberglass network from FOH to transmit HOGnet to the stage.
Or can I sent back the Artnet output from a DP8K back to FOH via the same network as I send the HOGnet to the stage?
