I wonder if anyone would actually make a Kirkish Chief Science Officer. An impulsive scientist, always wanting to be in on the action, yet having to be the mediator when tensions rose too high between the captain and the ship doctor. The romancer aspect would be optional. Someone could have fun with that role.

Not a requirement though. It might be better with no Kirkish person or the Kirkish one might be in a different field like engineering or navigation. The stars are the limit.
