The only thing you might be able to do is pair the devices to the stick using zwave js to update the firmware, but would have to remove and then add back to the hub after its done. From what I can see zwave js cannot join the stick as a secondary controller.
Yes that actually can work because it would begin the paring and the hope would be it fails the S0 bootstrapping and pairs anyway. May just fail totally though and not work afterwards.
On a C7 though, if you do get it to partially pair but its not working, and security says "None" you can reset the device, then refresh the zwave node until you get the replace option. Then do the replace to join it back in, it should join with no security into the same node and complete the pairing.
