(Has any consideration been given to an actual metafunc mechanism more directly analogous to metaclasses, that would be given the pieces of a would-be function (name, param names, default args, code body, etc), so that there would not necessarily ever be a standard function object?)

Deconstructing a function like that is too invasive -- I don't want to touch the calling sequence, for example, because it's so performance critical. None of the people arguing for decorators has shown a use case for that either. However, if you really want to do that, you can take the function apart and construct a new one using the 'new' module.
