Hmm, interesting idea. Going from this you could have some kind of unique secret victory condition for these advisors as well, which is different from their teams goals, so they do not just try to get their team to win. Maybe like letting them try to leave only nonastral nations (from whatever team) on the map when the game ends (fixed date), so they can enslave them easily. Or have nations with powerful women dominating (Sauro and Ulm and I don't know...). Sorry if that was already the idea.
