My Theories (Which are unlikely, for they would be unfair to the plotline):

1. Drizella (The reason it could be possible is that Drizella no longer has magic,so she's not a witch, and she's probably a different evil - Rumple level, let's say - and set on taking out the Coven to destroy Gothel and avenge her mother. Plus, Drizella was a member of the Coven, and was awake the whole time, she'd know who the members of the Coven are, and who their cursed identities are - i.e. in theory, Dr. Sage is a witch/part of Gothel's Coven. However, this won't happen because Drizella probably reforms because her mother died to protect Drizella, so she hopefully will align with Regina and Zelena to help break the curse without risking Henry's life.

2. Rapunzel (I have no evidence. The only reason I have this theory is because of Lucy reading the book in 7x12 promo, say, "Or if True Love shall ever break the curse, Henry Mills would surely die." This stems off of how Zelena was supposedly dead but ended up taking the place of Marian. So, why couldn't Rapunzel die and have her energy be transferred into Lucy? But this won't happen because it takes away Rapunzel's redemption in the end.)

3. Anastasia (No evidence. Just a quick thought, because this is impossible because Ana is a symbol of goodness and purity.)
