They would be good acquisitions, but Quantic Dream and Konami aren't having any trouble, they're very well. Ready at Dawn did shut down in August, so I assume Sony can't buy it.
Regarding new studios, Sony has minimum 2 new ones in the works: the one with ex-Deviation devs and the Bungie spinoff. And well, it isn't really a new studio, but they also have Haven.
Quantic Dream hasn't put out a game since 2018... 6 years and counting and they aren't having any trouble?
They don't even have a release date for Star Wars Eclipse and rumors are there have been development issues.
Konami gutted their AAA development and are now contracting out their IP to 3rd parties hoping for the best.. What happens when they run out of games to remake?
