Great. Yes, that works fine. I had a sort of solution of my own -- which
didn't work (and was inelegant anyway) 
Then your code didn't work either -- which could not be ;) 
If found out it was simply that the above settings were overwritten by
'dired+'. I adjusted it so that dired+ understands it too, and added
these lines additionally:

(defface diredp-display-nry '((t (:inherit secondary-selection)))
  "*Face used for files with \".nry\" extension."
  :group 'Dired-Plus)
(defvar diredp-display-nry 'diredp-display-nry)

(add-to-list 'diredp-font-lock-keywords-1
             ;; see dired-ignored-face entry:
             '(eval .
                    (list "\\.nry$"
                '(".+" (dired-move-to-filename) nil (0 diredp-display-nry)))))
