Of course that's the ideal solution, and of course lots of people have
done (or tried) exactly that and it often works. But I doubt very many
people are going to have much luck getting their neighbor to replace
their cheap solar converters with better ones, and I doubt many people
are going to convince the owners of the adjacent condo to replace their
cheap wall warts ... especially since lots of neighbors aren't all that
happy to have hams next door in the first place.
And hams that live in urban areas with industrial businesses nearby
aren't going to get very far at all.
If it was as simple as you pretend, rig manufacturers wouldn't have
bothered to build all sorts of noise reduction features into their
equipment.

Has anyone given thoughts or efforts to finding and addressing the
source of the noise? All of these electronic concepts are great, but
would not finding, reducing or eliminating the source be more
effective. I seem to think so from my personal experience of
tracking down noise and resolving same.
Start with the radio on a battery as the power source. Then drop the
mains power. Note the noise level. Then restore mains power and
observe the noise. That my friends is coming from your house. This
should be easy to find and correct. Power distribution systems noise
are more challenging to find and correct. But with a bit of
cooperation from the power company that can be accomplished as well.
From my experience and work, my noise level on most all bands, 160M -
6M, is S-2 to S-3, excluding atmospheric noise of distant lightning.
Winter will correct that.
