what if we specify the same domains with ws⋮// ?

Nope, because wss and ws listen on different ports the same way that http and https listen on different ports 80 and 443 respectively.
Someone would need to have intentionally setup a relay that wasn't encrypted so that anyone using the relay would have their IP address and other details available for the entire world to track.
The only way you can use a non secured socket 'ws' is with a TOR encrypted tunnel which means the socket is still encrypted anyway.
