Making a PlayStation OS for the PC would really be a waste of time in my opinion, not because Sony could not do it. No because its really not needed at this point.
Maybe for as a playstation mobile Phone esk Android OS based loaded on a product line of Gaming phones. In other words drop all xperia, and just make a playstation Phone and promote it like the PS4.
Dual shock 3 & 4 support
Runs on Android. And opens up publishing games on the google playstore made by PlayStation for a Mobile game platform.
Sony making exclusive mobile games on Google play as a publisher would be far better than trying to support & promote a PlayStation OS on PC.
Cross buy /cross play on Sony's Living room playstation console, but for mobile Playstation set up publishing on Google play as a publisher and developer for content. Google get 30% Sony 70% standard rates for any publisher.
