MCDEdit requests are in another place I think. But I could answer here.
This "add random noise" is a quite common thing for graphics editors. But it starting whole new editor section: Filters. Need to collect all really __useful__ filters, used by pixel artists, before starting that.
But.
Considering the topic, this "random noise" is not something that could work for wind or anything else. It really won't make sprites look any good. Pixel artists need to control each pixel value, without any "randomness". If you want to me to add this to MCDEditor, just make quick ugly "animation", I won't connive at this. Sorry, MCDEdit is not for "quick requests". If you want to make every tile noised - you can make "flat" animation, export these expanded sheets as pngs, edit them in any editor with this "noise", and import.
