Here's what I think they could do. Allow fellowship at the Kingdom Hall but not elsewhere. From their point of view it would mean they were still in control (You can see your grandchildren - just attend meetings!!!!!) but could tell the authorities that they aren't splitting up families etc. The talk would probably go something like this "EVIDENTLY when Jesus said observe the lillies of the field, he meant you can associate with disfellowshipped ones at the Kingdom Hall" (Note - I'm being sarcastic)
Their recent change in emphasis about the prodigal son could have prepared the way for this.
