Hi all,
Thank you for this great thread.
I recently bought also a ZB-GW03 v1.4 gateway.
Inspired by @syssi and @tube0013 GitHub repo I connected a Z-Wave module (zooz ZAC93) to the ZB-GW03 … and it’s working 
.
Also modified the case a bit by cutting some parts away so the additional PCB will fit and adding some magnets to the bottom side.
Here some screenshots:
