You can put to rest your claim that the five who signed aren’t opposed by the vast majority. If you want to be machmir like those and wear a synthetic toupée, gezunter heit.
As far as Vihyisem N’kiyim, there’s still a vast majority who don’t have a problem, as evidenced by the fact that their wives wear natural shaitels. Your tayna of “You are just covering Ervah with something that looks exactly like Ervah” is silly because issur isn’t showing something which looks like ervah, the issur is showing ervah.
