If the local chapter says it's cool, go for it. The idea that a raptor-kin breaks the 4th wall more than a 16 year old kid in a tabbard and make-up portraying a giant ice troll or a fierce hated opponent asking what spell you just hit him with is a little silly. Everyone has their own style and opinion of what is the proper way to play. I mean, we have character costumes from literally hundreds of years of history all mashing up in one time period. At any given event you can see a samurai, pirate, knight, Victorian noble and cave man hanging out in a light bulb lit tavern.
