I remember CBS tried that approach where they had the CBS Local O&O Anchors do the weekend CBS Weekend News in 2020 when CBS had to wait for approval to open the New York offices of CBS News due to the COVID-19 scare in New York City area when it started and they had to take over the set of the Late Show with Colbert for the CBS This Morning for the New York operations for CBS News and Washington DC for the Evening news and the other places where CBS has an O&O such as Los Angeles, Chicago, Boston, Dallas and others as representing "Middle America" in their weekend newscasts and in the case of San Francisco the KPIX Crew even took over CBS New York feed along with the other O&O's during the New York office closures.
