Will we EVER be able to glamour gear that we cannot wear???

How do you know that?
Are you so knowledgeable of the engine that you know that there isn't a variable they can toggle to allow an item to be glamour despite being unable to equip it?
Because if there was such a variable, then it would be as easy as just adding in an all-class item of the same model into the game, and it would require less content to be added.

You doubt that copy/paste gear models and give them the "all classes" tag or changing the classes restrictions of already existing gears is easier than changing the glamour feature?

Also, the first one still give the devs control about what can use as a glamour on all classes, like no AF.
