I can see a CBS newscast at 11 AM outside the Eastern time zone, but there are five stations which run Y&R at 11:30: Los Angeles, Chicago, Dallas, Nashville, and Springfield, MO. Also, KFMB has a local newscast from 11-12:30, delaying Y&R to 1 PM.
In the Eastern time zone, you seem to be suggesting that CBS's newscast air at 1 PM, directly opposite GMA3 and NBC News Daily. Do you think people will want three news/public affairs shows head-to-head in the middle of the day? And does Y&R get the boot? Perhaps those five stations that run Y&R at 11:30 expand their midday news (or, in Nashville, "Talk of the Town") to 11-12, then go along with the East Coast with network news at 12 (CT/PT).
The question then becomes: what happens to the soaps? It looks to me like B&B is headed for the boneyard sometime in 2025, and the new Black-oriented soap The Gates is still on the drawing boards. Does Y&R go to 2/1? And a few other complications: there are CBS affiliates (WBTV Charlotte and WANF Atlanta among them) that start their news blocks at 3. That doesn't bode well as a potential timeslot for a soap; further, I don't see CBS giving up Let's Make A Deal, which seems to work just fine either at 10 AM or 3 PM. This is a truly complicated situation.
