You should check out this thread: My wireless Smarthub for pairing
I’ve used that approach quite successfully to move my hub. The only place I actually needed it was for a door lock, and I didn’t want to remove the lock.
Be aware that for some devices, including directly to the hub is required for full functionality. This includes locks, and z-wave dimmers that have instant on reporting (e.g. Leviton VRMX1). Those devices can be included using a Minimote, but won’t function correctly. For other devices, the Minimote works quite well.
