Here's an idea and it's based on something they've done before.
They may tell the JWs to sell their homes and all their material possessions and move to countries 'where the need is greater'. Give the money to them and they will supervise this work worldwide. For them it will be a demonstration of their trust and faith.
They could say that their internet presence is sufficient for Western countries to carry on the work along with the few brothers and sisters that cannot move, such as the sick and elderly. The numbers are not growing in the Western countries, whereas in the poorer countries there is a lot of potential and they don't have easy access to online preaching.
Such a radical move would go along with the comments made in their latest mag-
"3) At that time, the lifesaving direction that we receive from Jehovah’s organization may not appear practical from a human standpoint. All of us must be ready to obey any instructions we may receive, whether these appear sound from a strategic or human standpoint or not. (4) Now is the time for any who may be putting their trust in secular education, material things, or human institutions to adjust their thinking. The elders must stand ready to help any who may now be wavering in their faith."
The added benefit to the org, along with all the money, is their total reliance on them for their future financial support, they're even less likely to leave once they've talked them into doing this. It also goes along with their number one focus - the preaching work.
Imagine the publicity they would get with a sudden mass exodus of JWs and how close the JWs would think the end is with such a strong call to action.
