Large Herb to a Carn?

Is it possible to make a large herb (example Edmontosaurus) into a carnivore?

yes just change the tclass im warning you dont put the tclass=trex or charca or spino or allo or any other large carn becose of grab and shake animation

Or a dilo tclass

How do I make it hunt other animals and humans?

Of what I know about modding, it's impossible. I tried making Ourano an Arizonasaurus (a crocodilian related to Postosuchus), but to no avail. I believe that the only sucessful diet mod is carn to herb.
