It's impossible to override ‘message’ with something like

  (advice-add 'message :around
              (lambda (orig-fun &rest args)
                (if (eq (selected-window) (active-minibuffer-window))
                    (apply 'minibuffer-message args)
                  (apply orig-fun args)))
              '((name . message-minibuffer)))

because ‘minibuffer-message’ has ‘message’ calls
and this goes into infinite recursion.
