Your choice is a tough one. DA'ing would be a personal declaration of your rejection of the religion and would mean quite a bit to you. But you've worked carefully to achieve your current status.
People typically fade and avoid DA just for family. Some try to retain friends also.
Despite your family shunning you, you make this statement:
"I feel that DA'ing puts up a wall, another barrier that prevents family from waking up and reaching out to us. As of now, they could more easily reason that they could talk to us. If we DA they really face a whole other level of difficulty in reaching out."
If it were me, I would stick with my faded status and reach out to family slowly at opportune times like weddings and funerals and any times when non-JW family invites us and JW family to the same gatherings. DA is for life and many situations may come up in the rest of your life- illnesses, births, deaths, joys, tragedies.
