Here's a list of people from the studio side that you could put in charge of the Studio Business Group and why they wouldn't make sense.
Kazunori Yamauchi - Been with Sony since the 90s, but all he cares about is cars. Polyphony Digital has also had a lot of difficulty technically and getting games out in a timely manner. Gran Turismo had a rocky period on the PS3 and PS4. No evidence that he could manage multiple studios.
Formerly Ted Price - Ted wasn't internal to Sony until 2019, Insomniac is above average technically but not top notch and they've really struggled generating IP.
Neil Druckmann - Has limited experience being studio head and is extremely busy with multiple projects. I could see him replacing Hermen when he's finally done creating games himself, though I'm not sure that will make a lot of people happy.
That's really the whole list...
