Oviraptor Hyena-Analogue

An idea I had about an oviraptoran hyena analogue. Instead of using that robust beak for smashing clams open, it would be a bone-crusher. With the hooked ends of the beak to tear flesh and the solid shears at the rear reinforced by a sturdy palate, they'd be cooperative hunters and scavengers, exploiting the resources left by the less efficient dromaeosaurs. Their evolution would mirror that of bone-crushing hyenas as the cleaner teams of the saber-toothed cats. When hunting live prey, the hooked ends of the beak would act similarly to fangs in a felid, as grip for the killing throat-bite.
(note - this is not the final version)

Thoughts? I'm thinking about oviraptors for the world right now...

Update - I've re-done this design, which can be found here [link] .
