This could cut rendertimes a bit. On low sampled render it will be total fine detail loss, but on higer sampling with low noise, i think it should do good job.

there are multiple papers on similar topic. I am planning to try it one day, since it should be easy to implement such algorithms into Corona. The only problem is that they usually require huge amounts of RAM (tens of gigabytes) even for simple images

To minimize RAM usage, i think it could be real-time adjustable region on render vindow that shows denoised result, and when render finish sampling, denoise image with something like bucket, or scanline to avoid put all image data into RAM at once.
