SQ to CQ staying digital

Hi Everyone. I am trying to use my SQ5 as the front end interface for all the mics, monitors, etc., and run outputs to a CQ 20, which acts as control for the house EQ, peripheral mixes, etc.. Any suggestions on how to do this and stay in the digital domain (ie not using the analog outputs, which then, obviously, get converted back to digital on the CQ)?

I have Dante on my SQ, but with no Dante on the CQ, I’m trying to figure out if there’s a way to stay digital before the final outputs?

Any suggestions?

Only thing I can think of is a crazy idea of taking Main LR and Mixes out USB-B to PC, then use a virtual Audio interface on the PC to route those channels back out to the CQ USB-B port…..BUT this will incur latency, which, for the Main LR isn’t a major problem but for Monitor mixes that isn’t a great experience for the musicians on stage.
