So generally, the NIST wasn't quite sure, but they felt like doing some random stuff would make it more.. random? ;)

Yeah but that makes like 2 additional lines, still nowhere near the NIST algorithm

As for the flaw in idea 2: That is correct, thanks for pointing that out. As for addition of entropy, what about hash(state || new_seed)? The fixed-length output can also easily be fixed, that's not really a concern I'm afraid.
