I think it would be an interesting addition, that if a reaped player gets executed during the day it would not reveal his role.
Instead the role would show something like “Empty Hull” or “Lifeless Corpse”. This would add much to the paranoia since the surviving players would not know what role is missing, except from the journal. Maybe only physician should be able to identify the corpse role with 100% accuracy. Priest can also talk with the dead to find out the role, but the dead can lie to the priest.
This would possibly cause the unseen or cult not to know if prince or any other important class is still alive. And the BD would not know if the MM is dead or they killed an important ally.
