Wireguard and udptunnel ? Any expirience on WG over TCP/443?

I was using udptunnel from this source https://github.com/rfc1036/udptunnel - that is important as I've seen other program with the similar name but different capabilities.
Here is the server side configuration (not OpenWrt though):
udptunnel -S --server -v 0.0.0.0:12345 127.0.0.1:51820
51820 is a default UDP port WG server listens on
12345 is a TCP port that is exposed to the outside world

Client side tunnel configuration is pretty much the same, something like this:
udptunnel 51820 {server addr}:12345

WG client should talk to 127.0.0.1:51820 instead of the real server ip and port.
