I should add that you can also do this without Icicles - Icicles just makes
things easier.

Function `dired' will accept a list of file names as its first argument. That is
the key here. This is all you need, to open Dired using a list `file-names':

(dired (cons (generate-new-buffer-name "My Dired")
             (nreverse (mapcar (lambda (file)
                                 (if (file-name-absolute-p file)
                                     (expand-file-name file)
                                   file))
                               file-names))))
