I think not.
We’ve been bathing in private for the past 200 or so years hereabouts. It is difficult, if not improbable, to reverse such a trend in society and culture so quickly.
While I may actually feel this is a thing that society might benefit from; I don’t see this happening outside of nations with a lower societal taboo, and more robust cultural norms and practices on the subject of nudity. It works in Japan simply because that’s how their entire society has been structured from the start, and their society largely agreed that communal bathhouses made much more sense logistically and economically; largely due to the fact that it is an island nation, and land space is more precious there.
Furthermore; I personally also prefer privacy. As a trans individual; that privacy is strongly necessary to me for many valid reasons concerning my own safety and health; and for ensuring others do not feel unsafe; regardless of their reasons for feeling that way.
Society is not ready for this kind of thing anymore and has mostly chosen to abandon the practice to antiquity.
Fwy uses her own set of neos sometimes; in context when it makes sense among friendly folks.
So Fwy/fwyfwy/fwyself are all words you may occasionally see fwy use. Fwy doesn’t make others use it though, we do appreciate it being used though; if someone addressing us can pickup the subtleties of it well enough to make the attempt. (Fwy promises it’s not complicated)
Fwyself personally does use normal pronouns as well; such as She or singular They too; it helps confuse people less. Fwy sees no reason to throw up a barrier; only provide people subtle ways to signal intent or speaking context through either normal pronoun usage or fwyfwy neopronon usages; as that helps Fwy quickly route and allow the right entity to respond more quickly if they are used.
No one else in our System has ventured to publicise any neos yet besides fwyself; they simply don’t seem to mind not having done so; particularly since using neos can get one singled out for harrassment fast in some internet communities.
