It's a bit cheating but the dash package has a -permutations function
which does the job.

(defun acronyms (word)
  (seq-filter
   (lambda (acronym)
     ;; TODO: check if acronym is actually a sensible word.
     t)
   (mapcar (lambda (lst)
             (mapconcat #'char-to-string lst))
           (-permutations (string-to-list word)))))

For the TODO, you could probably use some dictionary file.
