I still think the "mental" part is meant to be a red herring. It doesn't sound fairytale or legend or myth or anything related to Once at all. So I'd go with them as Brothers Grimm, and they will tie to another Author arc. This arc might explore deeper into the Author mythology, some past Authors like Andersen or maybe even Scheherazade, which leads to an Agrabagh arc. It would be nice if they also incorporate Will and Wonderland elements on 6A, and bring him over to 6B to confront Jafar, therefore resolve his storyline in the end of season 6.

Speaking of that, now I support mixing these two theories: Brothers Grimm in the asylum, tying to some Wonderland elements LOL.
