That's (practically) impossible--_Coelurosauria_ is stem-based (_Aves_
not _Allosaurus_), while _Maniraptoriformes_ is node-based (_Aves_ and
_Ornithomimus_).
Equivalent in content, I guess is what I meant. If ornithomimosaurs are the
next outgroup up from the clade containing _Allosaurus_ - as recovered by
the (admittedly imperfect) analysis shown in Suppl. Fig. 3 of Göhlich and
Chiappe (2006) - then Coelurosauria (stem-based) and Maniraptoriformes
(node-based) include the exact same taxa. However, I'd be surprised if
future analyses continue to find tyrannosaurs outside of the Coelurosauria,
or that ornithomimosaurs are so basal.
