My only problem with your reasoning is the Hungers are not as they are presented in the text a plot starter similar to the Agendas or the Refinements at least in my experience with players. They are too large for that. The big reason is the text doesn't embrace Beast's crossover nature enough IMHO and so the Hunger is easy to sate while acting a petty asshole and never entering real conflict with anyone;

It is debatable if Beasts need societies like presented in the Player's Guide but I would argue the Hunger have to be detailled to fill their role. My solution has been to narrow...
