Geoffrey Jackson spent 20 minutes accepting the position that it is not scripturally prohibited for women to be used in the investigation process, although probably not the JC itself (he said he'd check the scriptures on that bit, but we can guess the outcome).
Look out for the wives of elders jostling for and gaining these positions. There will be no better opportunity for gossip mongers to raise their status in the congregation than being officially involved in the intimate private business of others in the congregation.
Think of the power they will have in advising the elders on a JC if she thinks the victim is credible, with her opinion, bias and embellishments on the details. I wouldn't fancy the chances of a victim who has previously fallen out with one of these 'helpers'.
Whatever next, sisters handling microphones??!!
