Multiple Energy Meters on US 400A service (2 feeds)

I have a Dual Quattro 5k 120V USA split-phase configuration with EM530 energy meter and Cerbo GX. It works great! However, the house has two independent 200A feeds from the meter base, so I am only metering one of them. I’d like to feed excess solar into the other feed for the remainder of the house, but never ever export anything to the grid. Will adding a second EM530 on the other panel work if both are called Grid Meters (i.e., will they add up?) or will the Cerbo TX get confused?
