I have considered it in the past but it's a suicide to do it that way, let me explain...
You will have some traffic for one week then the page will die and be forgotten, unless you are ready to start from scratch and rebuild a following, which takes years.
If you watch the popular section on the website, you will see that outside of a few exceptions, only the older pages that turned into free without creating a new page were able to keep an healthy playerbase. It's because they don't loose their followers, which took them years to have, this is unlike what happens when you create a new page.
Hope that explains it and I also rather wait for itch.io to support paid NSFW content again than play around the rules.
