I don’t think we would see any of the others in SB. I think Whale was brought over specifically because he had a connection, and Regina wrote particular people into the curse to take with her. For example she takes Jefferson from Wonderland, but she doesn’t take the others from there because she doesn’t want them/know them (not taking Cora, for instance) Whale was someone she knew and either a) had a purpose for or b) She knew what he did to her, and wanted to punish him.
