Counterproposal: Just use SHA512.
There isn't any evidence that any SHA2-based hash algorithm is going to
be broken any time soon. If that changes there will very likely be
decades of warning before a break becomes practical.
Having just one hash is simpler and using a well supported one like
SHA512 may make things easier than using something that's still not
very widely supported.
