I get this idea is long shot and generally a waste of development resources. That point aside I don't understand the position that having someone alter another's appearance especially when outside of a few outlier situations the persons who appearance has been altered would not even know.

I mean so do not get me wrong I love walking around IRL in one of my extensive hentai hoodies. Though if someone developed the tech to alter appearance of others only to themselves. I would personally not care I still would gain enjoyment wearing what I enjoy.
