#12 should be a bit easier to do if playing with a bunch of writers. At least in theory. No idea if that would work. It’s just as likely to fall apart if the players don’t mesh. However for the average player, there may be some strategies to help out with that. All the stuff I can think of would require at least one session of an honest open discussion of what kind of story to tell/play. It’d be something of a pre-character building session, which sounds a bit weird.
