you can do that with google cardboard and application carboard. I think you can do that with Oculus too, but only problem is that 360 stereo image is fake, program split same image to create fake effect for each eye. If you render 2x360 images for each eye, you will have 2 flat spots where each eye have same image position. You can try if client doesnt know how 360 works he wont even see this problems
