Actually, Goldilocks was adapted by Disney in the 1940's. Every single story on Once and Wonderland (minus Rumplestiltskin, Snow-White and Rose-Red, Three Billy Goats Gruff, Beowulf and something else I'm currently forgetting) has been adapted by Disney into either a Disney Canon movie or a short. Or Mickey Mouse special.

And Once would be in the middle of its 6th season when Moana comes out, so if they make it to season 7 (which they most likely will), they'll probably do her if she's popular enough. I don't see Sofia or Kilala happening because while both have fairytale-ish stories (Sofia's mother is basically a Cinderella story and Kilala is 100% original like Merida), Sofia is a Disney Junior show while Kilala is a fairly obscure Manga.

That being said, I could see all of the other princesses showing up at one point or another, since they're all part of the Disney canon. While Princesses like Tiana, Megara and Jasmine would bring in viewers because of their iconic appeal, Princesses like Eilonwy, Kida and Esmeralda would benefit from being on Once because their Once appearances would shed light on their underrated movies. That actually would be better received by casual viewers, who thought Frozen was very much jumping the shark, and will likely see Merida the same way.
