Boro, if there's just one day in the middle of the game when you can't make it to the deadline, I don't think that's a problem. I'm sure there has to be one 'downs ww player who can't/ doesn't want to play but would happily be your one time substitute mod and start the Day/Night if you leave them instructions.
I like the Beast Hunter; I'm not a big fan of the medium/representative thing to be entirely honest but that's just a personal preference - I think it would work nicely with this array of rules though.
As for the Nightmare wolf, I need to think about it a bit. My original fear was that we'd have a game where every Day some ordo claims to have been haunted and thus every Day the wolves have to decide whether they counter claim and put themselves in the spotlight or let it slip past and let the village have a "known innocent". That would really suck for the wolves. But the updated rules already look a lot more balanced.
I also think it would be interesting if the Nightmare wolf was a specific wolf and the wolves would need to strategize around sacrificing them.
