I normally use my gender bender as my “twin brother” in stories — you can do the same if you wish or you can change that. I really don’t mind! You can also choose to use just one or neither of them if you don’t feel they’ll fit into your story.
The officer roles sound the most appealing but it’s up to you, I don’t mind if you’d prefer to give them something else.
