to be honest, I'm not entirely sold on the creature design we've seen so far, they look a bit too 'Farscape -y' its a big galaxy but a few familiar species wouldn't hurt

There have been so many differing types of aliens in the SW Universe it seems almost anything would belong. I never watched Farscape anyway. I dunno what the absolute criteria is for aliens in SW anyway, if you were to judge each aliens seen in all the films thus far would they pass, why and why not? Who's to say?
