I think that ornithologists and molecular biologists can strongly argue
against such a position (presumably you mean the hoatzin diverged before the
hesperornithoform-ichthyornithoform-neornithine clade evolved).  Or,
alternatively, that the fingers were lost several times in the evolution of
ornithurine birds.
