I think that's how the raytracing already works. renders at super low sample rate and gets a grainy render, then AI filter magic time.
The issue with using this for pixel art is that you really should be using a deep filtering which has been trained using pixel art training data. But who wants to manually up-res down-res thousands of artworks for training data?
With a raytracer it is easy, you just render once at low samplerate and then at high sample rate and use these as training data.
