I think there's still a chance of Alice II being a female Mad Hatter. She seems fairly mysterious -- we know she's been on set multiple times but she's never been spotted and the clip we got of her had her peeking around a building -- so perhaps she's another realm jumper. She might even be aware of the curse and actively working against Tremaine/Drizella/whoever else is involved.

I do like the idea of her being Will/Ana's daughter but isn't she a little old? The earliest she could've been born is nine months out of the pre-flashforward end of Wonderland, which is roughly concurrent with the end of Season 2 (I suspect). That makes her eleven years younger than Henry or, assuming Henry is 28 now, 17 (barring time shenanigans, which is a possibility given H2R). I don't know how old Rose Reynolds is but she seems older than that.
