MNINC:
Perhaps if one of the governing body members showed up to morning worship with a beard, that might do it.
On the contrary, it might show that they are lightening up and thereby attract some inactive ones to return.
Of course, it's impossible to just show up with a beard. Since it takes time to grow one, the scenario is unreal (perhaps your comments were meant to be?) and the GB members are so high profile and constantly in the limelight, they could never take off for a while and then grow one unawares. It would be nice if they did grow some beards, however.
