Possible? Maybe. Good? I doubt it. 
PSVR on PC was not good, basically just converted it to a 3DOF headset. Trinus did have a very limited 6DOF webcam tracking mode and you could use SteamVR for janky roomscale with multiple move controllers and PS3 cameras just like people do for full body tracking. 

For PSVR2 you need to look to where progress has been made for other inside-out headsets: This year Monado, an OpenXR runtime for Linux, implemented SLAM tracking that can potentially work with every HMD that has a camera. Currently WMR headsets and recently the Rift S have 6DOF for the HMDs and even hand tracking without running their respective propietary software. The controllers aren't 6DOF and there are issues with drift but it's not as unlikely as I first thought.
