Don't want to sound too snarky, but aren't you just saying that good denoisers must be temporal in addition to spatial? Something like an improved V-BM3D (cf https://arxiv.org/abs/2001.01802 https://arxiv.org/abs/2001.01802) and even traditional V-BM3D works fine even on non-Gaussian noise. Together with external noise generation (something like https://old.reddit.com/r/AV1/comments/r86nsb/custom_photonnoise_grain_synthesis_tables_for/ https://old.reddit.com/r/AV1/comments/r86nsb/custom_photonno...) that'd support external denoising (pass the reference and denoised video to get the grain spec), the whole FGS thing would be much more interesting.
