comparing unique anagrams?

How useful would determining similarity of words by their unique anagrams be? For example: “ROBERT” uniquely anagrams to “BEORT”; “BOBBY” and “BOOBY” both uniquely anagram to “BOY”.

Is there already a comparison algorithm that uses something like this?

What potentially “interesting” discoveries might be made about vocabularical choices if you analyzed text corpora with this method?
