Henry referenced Chewbacca back in Season 4, but we haven't gotten Star Wars yet. Just because something is referenced doesn't mean it'll appear :P

I doubt they'll use Power Rangers, it doesn't seem to fit in with the classic literature/fairytales/Disney movies that Once generally does. I could definitely see the "Original Savior" being a player in the big bad's backstory (whether it's the Black Fairy or her boss), though.
