If they were not introduced before (like one being Leota), then those three being an established trio helps move the story along without individual backstories. I mean, the episode is titled Sisterhood. Mother referred to many things -- Lily and Maleficent, Emma and Snow, Zelena and Robin, Regina and Cora, Regina's infertility -- but Sisters only referred to one thing -- Regina and Zelena -- so who knows how many things Sisterhood will refer to.

The Sanderson Sisters have been suggested a lot. Maybe something like Gothel, Morgan le Fay, and Baba Yaga also happen to be a trio of sisters a la the Sandersons?
