ISTM the only reasonable thing is to have a random seed picked very early in the process, to be used to change the hash() function of str/bytes/unicode (in a way that they are still compatible with each other). Do str and bytes still have to be compatible with each other in 3.x?
py3k has tests for hash("ascii") == hash(b"ascii"). Are you talking about this invariant?
