Should be possible with the latest Daily Build, which will produce a side-by-side non-panoramic render (so, no headtracking) - in the CoronaCameraMod just enable Virtual Reality mod (stereo) *without* enabling a Projection type override. This kind of side by side should be viewable as 3D on YouTube, 3D TVs and monitors, etc, and I think should playback / view as stereo with the GearVR though I haven't tested that out yet to see which apps in Oculus would do so - anything that views side by side stereo videos would work though.
