Sorry... This is not an hypothetical question at all. This exact thing happened in the late 1970's with a view change. You were allowed to associate with family members as long as you had no religious interchange. I believe it was Ray Franz that wrote and helped to implement that policy. It was only a matter of a few years until they changed back to the beat them and shunning policy in 1982 and that is where we have been ever since.
I remember that now that you brought it up Poztate.
