Pale Emperor we are of course with you on your exit. I faded having realized TTATT some years before stopping going to the meetings. The consequence was that my wife became the most zealous JW zombie possible and would literally stand between me and my three young children when I wanted to speak with them. Everything I said to my children was edited by her for religious correctness. I was an incarnation of Satan as far as she was concerned. The upshot was that a gulf was created between my children and me... just what she wanted.
I say this because after a few years we parted and I handed the children over to my wife for the sake of her wellbeing not so much for the welfare of the children. She would have been even more devastated than she was to be parted from her children but in retrospect I would have rather have had complete custody, which I could have done on the basis of her unreasonable religious behaviour, which was recognised as emotional abuse by the social services.
So my thoughts are that you might arrange a watertight agreement through the courts as to the upbringing of your daughter. A case can be made on the basis that as a rational father you want your daughter to grow up properly educated and not forced into an irrational religious cult which places the life, mind, emotions and activity of its members into the hands of the JW governing body. It would be easier to exclude toxic JW belief if you were in a position to look after your daughter yourself.
Nevertheless it's early days and not an easy path ahead for the moment but you have shown your determination to follow your conscience and you will get support from us. All the best to you PE.
