I would say Jared is actually the most likely to come back; first of all, he's a meh-at-best child actor who has played the same role for six years, so he's the least likely to be busy. Secondly... flashbacks. Since Regina and Hook have been confirmed to be roughly the same age, that would mean either they were de-aged, or Henry was a teen last time he saw them. And even if he wasn't, he's still the main character on a flashback-based series, so flashbacks for him should still happen.

I'd like to think Gosh would come back but, unfortunately, they have little connection to the remaining main characters. Their only tie as of Season 4 was to Emma. Regina's interactions with them only went as far as where Emma was involved. If they want to bring characters from Regina's past in, Robin of Locksley, Serum Queen, and Zelena make much more sense.
