It would probably improve Faux News.
No help to CBS however.
You cannot fix Faux. They are walking the edge of the casm between the huge constituency of conservatism they don't want and the oversubscribed tapped out drugged out "liberal" market.It's a bit like SpaceX deciding they don't like the satellite launch business and wanting to go into the space tourism for frivolous divas business. If you don't like a successful business that you have, there is an option - sell it.
