No I don't think so. There would be state, local, and city ordinances that would need to be followed. Health code violations. The Department and Boards of Health would be routinely closing them down. Then STD tests done weekly on the actors and actresses (especially if it was a live porno) in front of patrons. Then public outrage. People would be upset. You know we don't live in an open society ..
I know that director Tinto Brass disavowed and disowned the Malcolm McDowell film
Caligula (1979) after he found out that Bob Guccione went back to Rome with Penthouse Pets. Giancarlo Lui and Guccione then hired a skeleton film crew. They broke into the film studios in the late evening / early morning where the movie was shot (on the cover of darkness), then took costumes and props, and had live lesbian sex scenes edited into the first of post-production work. Bob Guccione and Giancarlo Lui were then credited as the co-directors of the movie. Bob Guccione and Franco Rossellini were the producers of the movie.
They say that there was enough film footage to make five
Ben Hur (1959) movies. So anything was possible with the sex scenes that they already had plus the live scenes that Bob Guccione added later.
