Can you make a mode that you filter down to words that have an unambiguous spelling?
Turn the word into phonemes, and then try to reconstruct the spelling from the sound of the word. Highly rank words that have one obvious spelling.

That sounds like a good approximation: although it's more judging if the word is spelled like it sounds versus if it has just one obvious spelling.
