I would agree with trimming the PRs, you're looking at 50% of your players to be vanilla, which is 11.
You're currently on 8.
I'd ditch the Miller Masons (as said), if you wanted to keep it cheeky, you could make them neighbours instead where they don't have each other's alignment confirmed.
I personally don't see much worth in the treestump, so would ditch that as well.
As for the Dorito guy, maybe tweak it to an item vendor. Giving it agency would counter the bus driver if his item was redirected somewhere else.
Knowing more details on the Poisoner, it doesn't seem particularly useful. Maybe switch it out with a x-shot Roleblocker?
