I just thought of something if the ''Disclosure Project'' comes to fruition and World Governments admit ''Disclosure''.
I could see a few things happening with the rank and file
1) The Borg will publish a series of broadcasts and WT's about Disclosure being one of Satan's tools to trick the JW's about Universal Sovereignty. Many, Many JW's will accept the Borg's explanation.
2) Quite a few JW's will just accept the fact that ''we are not alone in the Universe'' and that we are just kind of a little ''Bay'' in an immense Universe.
3) A few would admit '' Well the bible doesn't say anything about God NOT creating life elsewhere, so let's accept the fact about ET life now!""
4) I could see a few JW's going off the deep and perhaps committing suicide. This group being amongst the 40-50 years group being in the Borg, after realizing being ''lied'' to for decades, and decades.
