are these things possible in the game ?

Hey everyone I had 2 questions I was wondering first if its possible to give the players mouth guards like they wear in real life if it was possible to make an edit to the teeth in the global or something and second I wanted to kno if it was possible to tighten the collars on the jerseys cause in real life they wear tight jerseys and the collars are pretty fitted I'd really like to see tighter collars in the game hope these things can be done

yes, but it would be for all CFs unless you edited a single player's headshape

and no, it isnt possible to make the moving jerseys tighter
