Another IDEA:
I've found in FF that the AI has become a lot better at beating me to Feral Bond and the Baron... heck, they've become a lot better at teching generally, it's a good thing for the sake of challenge, but it can sometimes lead to bizarre results like "(Lowest score pathetic civ) has created Baron Duin Halfmorn" and 2 turns later "Baron Duin Halfmorn has been killed!" Hate it when that happens, ha ha.
Anyhow, how about a RITUAL available at Feral Bond which serves as a consolation prize, possibly capable of being built by anyone, multiple times much like Rites of Oghma. Give it some kind of moon themed name or whatever, but the sole point of which is to create one or more werewolf units to start your own werewolf mania. At its simplest, it could be like Pact of the Nilhorn except it creates a couple lowest tier werewolf units for you to nurture. Alternately it could make that city eligible as a place for units of the right unitclass or minimum level to use an ability on themselves ("Submit to the Moon"?) which gives them werewolf abilities, maybe also with the drawback of starting Enraged (since a drawback of having to spend gold would be silly). It may mean your prized unit who you "Submit to the Moon" ends up dashing out of the city hunting for blood, hopefully they survive and lose the Enraged promo, maybe they die though, oh well. Of course, Law Adepts supervising newly minted werewolves until their first kill would be a counter to that.
I am not thinking about any prerequisites like "Evil civs only" or "Doviello only", nor a minimum Armageddon count (nor causing +5 to the AC either), but hey, it'd be possible. While the event is somewhat rare, that "A werewolf attacks your palace, do you slam the gates on innocents?" event that comes up would be a bit of a cruel prerequisite, wouldn't it? I.e., you have to choose to sacrifice some citizens and then the ritual becomes eligible for you? Might be a bad idea since the event is not guaranteed to come up every game, but hey, people manage to enjoy the game without a guarantee of Gaelan or Mary Morbus too.
Anyhow, again, just an idea of making some kind of consolation prize available if you miss out on making the Baron, but really wanted to explore the werewolf rush for your civ regardless. *shrugs*
