While Emma being Mal's daughter, and Lily being Snow's daughter is interesting, it changes the whole core of the show. If this was a plot twist in season 1, okay, but as we're at the tail end of season 4, it is too late for this to be done, without having massive repercutions to the whole show. It would also taint the reviewing of all the episodes up until that point. Besides Jen shares features with Ginny, and Agnes shares features with Kristen, which clearly shows how careful they were in the casting process. So like I said, interesting theory, but not gonna happen.
