Is this possible? (idea for a graphics filter)

Hello. I was messing around with filters in Regen the other day, trying to make dither-heavy games look good and wasn't quite happy with any of them as you either get a blurry image or the blending of the dither patterns doesn't happen (2xsai and such). So I made these rough sketches below, combining unfiltered and NTSC filtered graphics. ... 1185950715

From left to right (Regen and snes9x screns): no filter, ntsc tv filter by blarrg, rough combo mockup by me, snes screenshot comparison

(Unfortunately the quality isn't great in google photos but if you zoom in you should see the differences. Nevermind the brightness difference, I had to adjust brightness manually since the brighten feature didn't work with filtered screenshot dumps in Regen)

Is this kind of result possible with a general filter, or would it need to be more of a case by case thing with a new setting per game or even per background? Does it look good to anyone else? :)

A friend of mine long ago made a filter that looked for dither patterns and created intermediate color into these areas. Such approach could be similar what you are after.
I don't remember what came out of it though...
