That would be a very poor idea. Since different filesystems have signatures in different places, a partition may well have signatures for several filesystem types. Similarly, many filesystems leave the first sector alone - there may be some boot loader there - so if such a filesystem was created on what used to be a swap partition, also the swap signature will still be there. More generally it is a bad idea to start a guessing game. That leads to systems that usually work, instead of systems that work.
