Yeah, no. Any "proof of work" system that meets simple criteria is acceptable: Hard to solve, easy to verify. Hashes are just the easiest to implement, but they're not the only one that could work here.
Factoring RSA keys of different lengths would also fit the bill. If the "difficulty" could be arbitrarily adjusted it'd be no different from SHA2 in terms of effort required.
