It's standard to have at least two hashing functions. You can then simulate having x hash functions simply by combining those two.[1]

But, your question is entirely valid and I'm not really sure why you couldn't do that. It might simply be that the kinds of hash functions used in bloom filters (non-cryptographic) are not well distributed.

Fascinating, thank you! I'll take a look at the paper when I get back home.
