Signal relay (Zigbee, bluetooth/BLE) from one linux device to the HA device

Hey there. Not sure in what category I should post this. I was wondering: Is it possible to use a Zigbee USB dongle and the bluetooth chip from a RPI3 as relays to extend range of the HA server ?

I currently have HA in a container on a NUC. Works well. BLE works. But some BLE devices are too far for the signal to reach the NUC.

What I’d like to do is setup an RPI with rapsbian, enable Bluetooth, and have the captured messages forwarded to the NUC. Is this possible ?

And then, same question applies for Zigbee (even if right now I have no zigbee except HUE but I plan to acquire some).
