Orion SDK, Runtime 0.8 and **Pre-Orion** assets

Are there steps anywhere regarding how to make a basic VR scene using orion SDK, Runtime 0.8 but with pre-Orion assets?

All I want to do is get the PinchingSandbox scene from the old V2 assets and make it work with orion SDK + Runtime 0.8. I obviously cannot just copy-paste prefabs (i.e. make the LMHeadMountedRig a prefab and then move it over to the project that doesn't have the Orion assets) because then scripts like Leap Hand Controller and Leap Service Provider don't load (Using Unity3D)

Of course I can just tick "virtual reality supported" and I'll get the video outputting to occulus just fine, but I cant seem to solve how to get hands into the scene because the VR setup on the leap motion website assumes you're using the newer assets: https://developer.leapmotion.com/unity so I cannot follow those steps to add hands to my project

The PinchingSandbox scene is just a scene with a few blocks and a "grabbable" script defining how blocks react to pinch and grab strengths. Couldn't be simpler really.
