Our local wading pools and spray parks require a "tight plastic pants or diapers designed for swimming". Couldn't I just use our regular fuzzibunz without any inserts? Since the outer layer is made out of PUL, they won't let any poop leak out. Has anyone else tried this?

I don't really want to buy special swim diapers for LO, especially since we don't get that many hot days here so we won't be swimming every day or anything.
