Might something like this be what you're after?

--- BEGIN ---
(defun get-buffers-with-files ()
  (let ((wanted '())) 
    (dolist (b (buffer-list))
      (if (buffer-file-name b)
          (setq wanted (append wanted (list b)))))
    wanted))

(add-hook 'buffer-list-update-hook #'(lambda ()
                                       (setq buffers-with-files 
(get-buffers-with-files))))

(defun next-buffer-with-file ()
  (interactive)
  (setq buffers-with-files (append (cdr buffers-with-files) (list (car 
buffers-with-files))))
