Sure you could :) You just have to do it explicitly:

  def __call__(self, REQUEST, ...):
    if i_want_to_call_acquired_index_html:

      # acquire it from our parent, to avoid getting our own!
      index_html = getattr(self.aq_parent, 'index_html', None)
      if index_html is not None:
        return index_html(self, REQUEST)

    ...

        
  index_html = __call__
