It may be the case that I misunderstood the functionality of the Pygate. It looks like there's LoRa on the Pygate via the Semtech SX1257. If that's true, then my use-case would be resolved with GPy + Pygate. Can someone confirm that my original question had a flawed premise, and that GPy + Pygate would provide LoRaWAN gateway with cellular backhaul?
