Please please please refrain from paywalling any sort of fanfic. The lack of monetary gain from fanfiction is one of the core reasons we are legally allowed to create/share/read it.
Fair Use doesn't entirely hinge on whether or not we are earning money, but it is one of the biggest factors a court will consider.
The OTW (company responsible for our ability to legally create fanfic; also owns Ao3) already does so much for us legally, and we absolutely do not need to make their job any harder.
