No idea why it wouldn't be a good solution, only "negative" thing I
could find was a comment "FIXIT: Use a better equivalent to
custom-face-edit if there is one" in diredful.el:312 [1]

FWIW, in Org-mode (org-todo-keyword-faces @ org-faces.el:355-371 [2],
exactly the same use case) they do it like this:

    :type '(repeat
            (cons
             (string :tag "Keyword")
             (choice :tag "Face   "
              (string :tag "Color")
              (sexp :tag "Face")))))
