This will certainly make changes possible. It would even be possible for a CO to visit two congregations a week with a suitable rearrangement of meeting times. Or I could see COs being expected to do secular work for a day or two a week and get less funding from the Society.
However, my opinion is that the WTS will want to keep the CO arrangement in roughly it's present form. It provides an excellent return on investment. The Society needs COs to maintain control, advocate for building new halls or remodel old ones and "encourage" older publishers to put the society in their wills. The COs are salesmen and having fewer meetings will allow them to make more sales and boost the Society's finances.
I wouldn't be surprised if they start having assistant COs that work under the direction of the CO and make short visits to congregations between CO visits or visit troublespots and difficult judicial committees or help with incidents that could incur liability. They wouldn't have to be paid and could extend the COs power. It would also make it easier to see who are the best salesman that can be promoted to CO.
