Your plan works for the most part.
I'm currently thinking it over in my head of whether Lalendra should only out Icon's role if it's one of the scummier ones. But I feel like any role other than cop is at least somewhat scummy for the 1st draft order. And we can hardly say "only out their role if it isn't cop".
Everyone is expecting Icon to be cop anyway, so is outing his role really so bad? Besides, if Icon is outed as not being the cop, then that means scum will have to put effort into finding the cop which would distract their attention. Which likely means they'll start shooting people higher up in the list which potentially gives themselves away.
So I think Lalendra should out Icon's role regardless of what it is.
Any setup spec specifically you would like me to weigh in on?
I mostly just lurk now.
