WYSIWYG Vector outliner script

I have spent a fair amount of time with Illustrator over the years manually expanding appearances, outlining strokes, combining paths, etc. to get two-color art expanded into flat, outlined vectors. Doing this once for one piece of artwork isn't that big of a deal, but doing it for many pieces of artwork is bad in two ways: (1) it takes a long time, and (2) it makes the artwork uneditable unless I save a duplicate, which becomes a pain to track mentally. I'd like to keep an illustrator file of ~100 artboards fully editable, and then simply run a script to do the following any time I need to save out pngs from artboards, or otherwise export the art. For example:

If the images are hard to understand, I'm simply trying to take art that is black and white in appearance, and make black shapes out of the black parts. The script would create a separate .ai file so my original doesn't get expanded. Anyone seen anything like this? If not, any ideas about how to get there? I have little to no scripting experience.
