I think the answer to this is probably no; my understanding of the communication protocols is that the ME-U hub is the thing that supports Dante (and several other protocols) and then converts it to the dSnake protocol that is expected by the ME-1 units (also support AVB I think). That protocol going to the ME-1’s is unidirectional, and they don’t send anything back to the ME-U hub (the output ethernet port on ME-1s probably just forwards the exact same packet to the next device daisy chained to it).
Now, maybe a firmware update could make it send packets back to make it behave like an AR2412 stage box, but that would be a compromise if the ME-1 hardware is even up to the task of sending packets that quickly; the return signal could be at the expense of inputs that could be coming from an AR2412 that is hooked up to the system (stage boxes would also need a firmware update to handle incoming packets over their monitor port). For the ME-U hub, a firmware update to merge up to 8 (?) incoming packets together into one, and convert it back into Dante for a return stream — I’m guessing that is where the hardware is not up to the task; sending a duplicate signal to 8 things is easy, processing incoming data from 8 devices is much harder, and I imagine would require revising the hardware.
