This makes sense. However the implementation detail of h_0(x) could also be foo(x) + bar(x) or whatever. At the end, you have a function that returns a fixed number of bytes.
I doubt any has function that we use today changes the algorithm halfway through its operation though. So your proposal might have a benefit in security by obscurity way.
