Or just put a property with the old filename covering each filename.

  e.g., (put-text-property FN-START FN-END 'old-file-name OLD-FILE-NAME)

Since new insertions etc., will inherit this property (you'll have to
fiddle to get the edges working correctly), these properties should
remain as contiguous regions when the user is done editing, and finding
them should be a snap:

  (let (beg end)
    (setq end (point-min))
    (while (setq beg (next-single-property-change end 'old-file-name))
      (setq end (next-single-property-change pos 'old-file-name))
      (rename-file (get-text-property beg 'old-file-name)
                   (buffer-substring-no-properties beg end))))
