CUDA Vulkan interop

Is there a way to run CUDA kernel as callable shader in VK_NV_ray_tracing?

I have zero insights into this, but have you had a chance to look at the following sample app?

Yes, I am aware of all interop possibilities between CUDA/OpenGL, CUDA/Vulkan currently published.
All of them are just an import/export of a resources (memory objects, semaphores, fences) not an executable “code”.
