Personally, I don't think the writers truly meant "Black Swan" in any meaningful way, but that aside, I think that:

Emma as Black Swan, Rumple and Belle as Up couple, etc; Allusions.

Had to retype this three times, but....

We already have Emma as Dark Swan being an allusion to Black Swan/Swan Lake.

So, I say that's sufficient.
