Forcing players to be displayed in a way that is not in accordance with their wishes is, as far as
I know, strictly forbidden in this game.

There's no reasonable position to expect they would suddenly sanction such a change. Should also consider that most people cultivate an image that is largely centered on how others perceive them, rather than self perception, and thus it matters quite a bit for someone else to supercede that image.

And if people know without a doubt that all that effort is for nothing, you can kiss the glamour market goodbye. Why bother spending gil to get the latest look, or grind for the materials to craft it? Why purchase mogstation outfits?

Ultimately that's just a few of the many reasons it won't happen. And for all the opposition's talk of compromise, they've overlooked the simplest one of all: "get over it".
