Here's a simplified version of the ugly hack I use to do this.  

(defun rasmus/compose-mail (&optional arg)
  "Compose a mail with the possibility to choose a style if ARG is non-nil"
  (interactive "P")
  (require 'gnus-util)
  (unless (gnus-alive-p) (gnus) (bury-buffer))
  (if (not arg)
        (compose-mail)
      (let* ((accounts (mapcar (lambda (x)
                                 (let ((adr (cadr (assoc 'GCC x))));; TODO: fragile
                                   (cons
                                    (replace-regexp-in-string ".*:\\([[:ascii:]]+\\)/.*" "\\1" adr)
                                    adr)))
                               gnus-posting-styles))
             (choice (ido-completing-read "Choose account" (mapcar 'car accounts)))
             (gnus-newsgroup-name (cdr-safe (assoc choice accounts))))
        (gnus-summary-mail-other-window))))

You set that in your posting style as well.  Here's an example (the
eval line in the end).

  (setq gnus-posting-styles
        '(((lambda () (rasmus/gnus-posting-style-identify "school"
                       '("To" . "rasmus@school\\.edu")
                        (lambda () (pank/message-mailto-test "school\\.edu"))))
           (address "rasmus@school.eu")
           ;; (Face (gnus-convert-png-to-face (expand-file-name "school.png" gnus-face-direcotry)))
           (Organization "School")
           (GCC "nnimap+mail:school/sent")
           (X-Message-SMTP-Method "smtp server.com 587 rasmus@school.edu")
           (signature "My sig")
           (eval (setq smtpmail-stream-type nil)))))

Also, the X-message-SMTP-Method seems to be stripped from a quick test
(examining a raw message send to myself).

Hope it helps,
Rasmus
