The Flesch Readability Score was devised by Rudolph Flesch.
I used to have softcover editions of a couple of his books. They did a good job of explaining how to keep writing simple.
Quite readable - he practiced what he preached.

Offhand, I don't know of a copy-editing software that will hunt down and highlight the big words and long sentences. But it sounds like something that should already exist.
Keep searching, bet there's something out there, somewhere.
