I think it would be awesome if instead of Discharging a (comissioned?) Bridge Officer. that you could Demote them to a Duty Officer instead (available slots Permitting of course). Freeing up room in your Boff slots, and adding another green-purple Doff. they would get at least 1 if not 2 traits associated with their Species, this could be based on what their Traits are? and then 1 or 2 other random traits.
