Should models get paid royalties?

First off, let me state that I have no knowledge of how models are currently paid, but I presume that they get a one-off flat rate from the producer/studio at the start, who takes all the risk of whether the scene makes profit or a loss. However, I've been wondering if adding in some kind of royalty payment to the models once a scene recovers its costs and moves into profit might be a good thing for everyone?
It seems the big issue at the moment is persuading people to pay for porn, instead of watching it on tubesites or downloading it for free illegally. Yet at the same time, there has been an explosion in sites like [spam], where people seem to be happy to pay what are often relatively high prices for often not great content. I'm guessing a big reason for this is that they know they are directly supporting the girl in question (and maybe this is where you get this new phenomenon of so-called 'simps' etc getting off on chucking cash at girls).
If these people know that buying a scene on LegalPorno/AnalVids would lead to a percentage going to the model featured, would it encourage more of them to pay? Knowing that they were directly hurting the girl involved, and not just some faceless company? Would it also encourage the models themselves to play more of a role in promoting their scenes, and encouraging people to buy them?
Just some thoughts. Any takers on this, or is it completely unworkable?
