And thus, if I've understood you correctly, Maniraptoriformes would become a 
clade *within* Maniraptora.

The name "Sauriurae" has been much abused of late - by those who want to put 
_Archaeopteryx_, Confuciusornithidae and Enantiornithes together into a 
group that is separate from the Ornithurae.  Under this arrangement, birds 
(Aves) cleave into a neat-and-tidy Sauriurae / Ornithurae dichotomy.  This 
dichotomy currently has absolutely no phylogenetic support.

I'm not aware if Sauriurae (originally Saururae) or Archaeopterygiformes or 
Archaeornithes have actually received a phylogenetic definition.  Any of 
these names is available should the "long-tailed birds" (or at least some of 
them, including _Archaeopteryx_) be found to form their own clade within 
Aves.  I believe all these names (and "Ornithopappi") were proposed solely 
for the reception of _Archaeopteryx_ (including _Archaeornis_, and other 
assorted synonyms).
