It's possible, and this is closely related to adaptive sampling. It
will still require min/max samples to get some predictability, but yes
when it works it's easier to tune. Something to look into once, but it
needs to be done quite careful, because determining if there is any
noise you can only do statistically. Also compositing can make some
area of the image more/less noisy.
