If the organization is going to survive (not something I really want) it will have to completely change into something else. It's natural selection of a kind. For a long time, in an environment that seemed so big and frightening, they offered to their followers the ability to feel special and saved. Now that the theological underpinnings have been exposed as not being there - they have to find something else to offer their sheep.
Think about those old roadrunner cartoons, where the coyote runs out over a canyon and hovers for a moment... kept in the air by his sheer ignorance of his distastrous situation. That's the Borg, hovering above a canyon of annihilation, just waiting for one more crisis or hostile government to tear them apart.
If they hired me (at an astronomical salary, of course) to save them, here's what I'd do.
First I'd retire all the old blood on the GB and at the upper echelon, pack them off to Paterson and let them live out their days with the relics of the past, and have them buried decently and privately (no WT announcement, these guys are an embarassment). Hire some new boys to come up with a program of education.
Secondly, I would publicly retract and apologize for the following nonsense: 1914, blood transfusions, and holidays.
Those changes are going to cause enormous shockwaves among the faithful, so I'd have something ready to fill their void. Blood and holidays will cause a great deal of consternation, but 1914 will be the worst! Ergo, since the end is not coming tomorrow or even necessarily in our lifetimes, I would have a whole watchtower and public talks on how to live NOW. These would be prepared by my new guys. Talks on the changes coming up, easing of restrictions, emphasis on recruiting and KEEPING new members.
Now, what can the religion offer the faithful? How about health benefits? Members of the dub religion get good insurance from local providers, paid for by the newly chastened Borg and its vast coffers of wealth. This might help reduce the turnover, especially among the younger set.
A program designed to help out the older ones who have wasted their lives, as a way of a token apology, with their struggles, by emphasizing programs of good works and charity as opposed to mindles magazine distribution.
Finally, I'd get away from all of the technical details of disfellowshipping by making it only for the worst offense, not just fooling around as a teenager. Unnatural acts of pedophilia, bestiality, etc.
College and higher education and a more open minded view of science would be viewed as important.
That's what the Society would have to do to regain any credibility as a religion. But they are too concerned with appearance and tradition. Screw em.
