Yes I think this is the correct way to do it. Maybe you can add a copy method 
which did the conversion? It might come handy some other time!

  def copy(self, deepcopy=False):
      "Return a dolfin.Function of itself"
      from dolfin.functions.function import Function
      if deepcopy:
          return Function(self.function_space(), self.vector().copy())
      return Function(self.function_space(), self.vector())

and then from each of the hierarchy methods:

  def fine(self):
      "Return the finest Function in hierarchy"
      f = self._fine()
      return f.copy()

  def child(self):
      "Return the childiest Function in hierarchy"
      f = self._child()
      return f.copy()

...

I like the way the shared_ptr interface makes it possible to not copy data :)
