Here's my solution for (1) setting up Gnus for several mail addresses
and (2) cycling them easily in a message-mode buffer (using F9 key).


    (setq user-full-name "User Name")

    (defvar my-email-addresses
      '("primary.address@internet.invalid"
        "other.address@somewhere.invalid"
        "yet.another@invalid"))

    ;; Set important variables

    (let ((addr my-email-addresses))
      (setq-default
       user-mail-address (car addr)
       message-alternative-emails (regexp-opt (cdr addr) 'words)
       message-dont-reply-to-names (regexp-opt addr 'words)
       gnus-ignored-from-addresses message-dont-reply-to-names))

    ;; The cycling functionality
    
    (add-hook 'message-mode-hook 'my-message-mode-hook)

    (defun my-message-mode-hook ()
      (define-key message-mode-map (kbd "<f9>")
        'my-message-toggle-from))

    (defun my-message-toggle-from ()
      (interactive)
      (require 'mail-extr)
      (let* ((current (nth 1 (mail-extract-address-components
                              (message-fetch-field "From"))))
             (next (or (nth 1 (member current my-email-addresses))
                       (nth 0 my-email-addresses))))

        (when (and current next)
          (save-excursion
            (save-restriction
              (message-narrow-to-head)
              (save-match-data
                (when (re-search-forward "^From: " nil t)
                  (message-narrow-to-field)
                  (delete-region (point-min) (point-max))
                  (insert "From: " user-full-name " <" next ">\n"))))))))
