Yep, that might have been a good idea.  Something along the lines of "Dinoaves" 
- in the same way that the new name "Cetartiodactyla" was coined when whales 
(Cetacea) were put inside Artiodactyla.  

However, it's entirely academic now, so we'd all better get used to the bird 
clade (Avialae or Aves) being a subset of Dinosauria.  It will happen, in the 
fullness of time.  Eventually, placing birds inside Dinosauria will seem as 
natural as having bats inside Mammalia.  Phylogenetically speaking, there's no

Do you mean "Metaves"?  Metornithes was erected by Perle &c (1993) as a clade 
that includes all birds except _Archaeopteryx_, back when _Mononykus_ was 
thought to be a bird.  Since then, I've occasionally seen Metornithes used as a 
more inclusive theropod clade, in keeping with Chiappe's definition 
(_Mononykus_ + Neornithes).  Chiappe (1995) considered _Mononykus_ a bird; but 
now that alvarezsaurids are outside the bird clade, Metornithes can be co-opted 
for the clade that includes alvarezsaurids and birds.  This goes against the 
intent of the original definition, but what can you do?
