-d doesn't work, because of this code:

;; Include if the dictionary is in the library, or dir not defined.
(if (and
name
;; For Aspell, we already know which dictionaries exist.
(or ispell-really-aspell

(not ispell-library-directory)
(file-exists-p (concat ispell-library-directory
"/" dict-bname ".hash"))
(file-exists-p (concat ispell-library-directory
"/" dict-bname ".has"))))
(push name dict-list)))

Then it's not possible to add custom dictionaries (when using cygwin 
ispell) or dictionaries from other directory, than 
`ispell-library-directory', because they are ommited by 
`ispell-valid-dictionary-alist'.

Yes.
