I was thinking in this same direction also. It's a shame that Adam and Gabbie's little girl wasn't the 5th druid.
She would have knowledge of both fae and mortal, along with pure inocennce since she is so young she couldn't be affected or tainted by the death by sex fae and she would have all those big, strong highlanders to protect her. She would also would have the ear of the queen. Or she could be like the "Fifth Element" focusing all the powers of the four adult druids and directing it where it needs to go.
I know its far out there and I am not explaining it well, but you might get the idea.
