Are non host GSC menu's possible ?
If so, I'm thinking of some pretty cool ideas I just need someone to confirm if they're possible or not.

Not possible, GSC is executed on the host's side. So if you aren't host the .gsc files on your side don't execute.

CSC scripts are executing on clientside, I didn't tried to modify csc yet, you can try it by yourself.
