I'm not sure how durable these would be, but with the way they are installed, there wouldn't be much waterproofing needed due to the 3 strips of tape used, and one of the strips are literally right behind the zipper portion on your material. https://www.youtube.com/watch?v=ZsSofS6lcjM
Certainly an interesting concept, but I'd rather someone else try first
