I would say no. Revitalizing or reimagining something still requires creativity and skill from the person doing so. They’re interesting concepts to explore that offer their own opportunities that “original“ proposals lack. Besides, a lot of fan work is inherently based off of something else, even if an idea is completely new it’s still being designed as a take on what (regarding this site in specific) Disney Parks and the like set out to do.
I probably didn’t need to say all that but anyways once again, my answer is no.
