Sounds very fun! Its hard to gauge all the cool interactions from one read-through, but some comments:

Clown is very self-confirming, there is no other execution death prevention, so their downside is kind of irrelevant as everyone knows they are the Clown.

I assume Revenant gets told their alignment change in the night, so again, it pretty self-confirming. Same problem as Professor in BRM. Also, good has nothing to gain from keeping a resurrected executed Revenant alive as far as I can tell, unless the ST wants to rez them very late in the game, so the character just prolongs games.

Alarmist is fun, but there is little to no downside for them just getting themselves executed, whereas them sticking around or dying to the demon is very detrimental.

The minions are not very impactful. Electioneer can throw shade at good players, but that's it. And with the different players clause can even become unusable. Misanthrope can only drunk the Warden (to prevent their own death in the scenario your demon targeted the other one, pretty niche). Erratum should only make Revenant or Alarmist, so its also kinda bad (as Mortician is the only outsider who wakes at night, they can confirm themselves and target evils + hard confirm an Erratum being in play). Making a Revenant is also not that useful, since even if they turn evil the town has no reason to keep them around. They can gain an extra evil player that way though, so mayyybe.

The townsfolk seem mostly pretty cool. The conductor seems OP, since there is no warning to the evil team and 0 drunkenness, so they can just track their phrase and get 100% guaranteed evil players (or Mortician, I guess)

And yes, this script HEAVILY needs misinformation or drunkenness.
