As others have said not possible. I asked about this very scenario here:
This is what I plan to do:
I have a few Quibino relays and they are my least favorite devices and a huge pain in the behind to reset and get into pairing mode. So I will migrate my 80 Zwave devices to the C8 and manually repair my 100 Zigbee devices since zigbee resets are much simpler and my zigbee devices are more accessible than some of my zwave.
