If the COs are truly being phased out....
At first I thought that it would send shockwaves through the congregation, certainly the body of elders. Can you imagine? No more CO visits? Picture yourself sitting on a body of elders; all the preparation that goes into getting ready for the CO visit.
Making sure the territory book is up to date and that there aren't too many unworked territories or too many territories that have been out over 6 months - if there are to many unworked territories they must be checked out to someone quickly. If there are territories out over 6 months you must check them in and re-check them out again. Doing these things keeps the records safe for review.
What about the literature counter? Don't want to have too much overstock on hand. Yikes. Magazine guys have to watch out too. How many magazines do we order for our congregation? How many publishers do we have? How many magazines are placed each month? Doing this kind of math could end up showing the true waste. The magazine brother better watch out.
What about finances? Better have everything in order and neat.
This is only a small amount of the buid up to a CO visit. The actual visit can be a real pain in the keyster. Especially if it's a new CO to the area. He won't know who's who. Yes, he received a rundown from the previous CO but that doesn't always translate well. He'll try to change things in the congregation too. Each CO has their pet peeve and you just have to deal with it until they get reassigned. Some COs want to appoint everyone, some want to appoint no one. Some COs focus only on preaching and the territory cards, others barely care about that because they're concerned with the kingdom hall funds and how much excess or lack there may be.
Basically, you can tell from each COs talks what their focus is. Regardless of whether the WTS gives them the outlines or not they fit their own twist into things.
My guess is that is one of the things the WTS doesn't like. Plus the personal loyalty that COs often receive from specific bodies of elders. The CO is kind of a superstar in the dub religion.

However, given what I said above, I don't think the congregations will notice the change much. Whether a specific CO visits or a regular specially appointed elder visits and accomplishes the same things will not much matter to the rank and file. The elder body will notice; they'll have less respect. But the rank and file will go about their business and just schluff it off as a minor adjustment. After all, it's the same thing, the only difference is that the WTS has wisely chosen to use the funds we provide them in a more efficient manner.
