Is it possible to capture 16Bit depth with Stereo panoramic plugin

I am working on a GearVR game

I would like to use the the Stereo Panoramic plug in to capture 360 stereo screenshots of a level and then use those captured 360 stereo panoramic to display the game environment.

Only the characters and props would be rendered in real time.

The best way to render those real time 3D models and sort them correctly would be to render a 16bit panoramic depth map for each eye at the same resolution as the stereo panoramic.

Would this be possible and what would be the process to capture such panoramic depth map?

How should the material be setup to display the stereo panoramic and apply the stereo panoramic depth map to the z buffer?

Thanks a lot.
