Ok, here's a scenario to play with.

Rumple told Cru and Urs that Chernabog went after Emma (How he knew that I'd like to know). So let's assume for a minute that Mal is brought up to speed on this info. This fits perfectly in her prediction regarding Snow's child at the tree, so She's gonna buy it. (Besides, it is believable)

Regina's going undercover. However, After Regina gets in, she wants to have some help (partially in order to keep from relapsing to the Evil Queen). She can use her friendship with Emma as a way to get her in, but they are going to have to find some reason that the Savior would actually switch.

How they do that is have David and MM come clean with Emma. (maybe at first in private so that she can process the news, as whatever it is will probably make her upset, and you know that they are going to end up coming clean eventually anyway). Then she can storm off (with a little fireworks for effect, think the ruse that Regina used at the beginning of the Zelena Arc). Mal will hear of this (from Regina), and seek Emma out to talk to her, and that's how she will get in with the QOD. Mal is the Mistress of All Evil, yes, but she does seem to have a soft spot.

I know that scenerio is rough, but I think it has a chance. (and it puts Emma in place for the surprise Reveal of Lily as Mal's daughter).
