Police, council officials, lawyers and at least one sportsman are on the 50-strong list of alleged clients, according to an industry figure who is attempting to persuade a court to allow their identities to be revealed next month.
The evidence could be brought before a case in the capital following police raids on six saunas in June which resulted in a number of arrests and licenses being withdrawn.
The firms are due to appeal against the decision at Edinburgh Sheriff Court on October 4 and three of the saunas are understood to be planning to drop the bombshell.
An industry source said they would attempt to put the "roll of shame" before the court in an attempt to prove the alleged double standards of some of the authorities involved in the clampdown.
He said: "It's all really hypocritical that they can use the girls for many years and then as soon as Police Scotland say so they're suddenly condemning them.
"We've had all kinds of official men coming into the saunas, from councillors to police officers, most of them senior, and they're well known by many.
"They would come in, pay the £10 to £20 desk fee before going into a room with a girl, just like everyone else.
"Now they're telling us we can't do this anymore. It's ridiculous."
The source added that councillors who are recognisable faces across Edinburgh have been patrons of the premises.
Police Scotland and City of Edinburgh Council would not be drawn last night, but a former senior officer described the threat as "stupid". He added: "They are going to lose any public sympathy they have regarding the sauna closures."
One councillor said: "We've always known what goes on inside these saunas - in fact, it's pretty common knowledge."
