Vive Stereo Rendering Toolkit broken in VR LWRP

The HTC Vive Stereo Rendering Toolkit does not work in the VR Lightweight Render Pipeline, presumably because the materials are based on the standard shader.
Has anyone found a solution to this, e.g. a way to convert the shader to a LWRP version?

I noticed that the Portal surface uses the Custome/StereoRenderShader that has the directive:
"#pragma surface surf Standard"
in it, but the 'Standard' here refers to the lighting model, not the Standard shader, or is this something that can be replaced with a LWRP compatible version?

 

It's not a surprise that these SDKs collide

 

Hi, I have the same problem too. Have you figure it out ?
