After having raised Nate, I would say keep her regardless (and don't bring that baby anywhere NEAR a pest control place!) They bond really tightly with their humans and I don't believe they would ever wild up sufficiently to avoid being chow.
That little mouse in my basement that I set up for soft release FINALLY is spending the majority of her time out of the tank (though she still returns for a bite to eat and a spin on her wheel!!) but even though I literally did not touch her safe for picking her up and putting her in the tank the first time and did everything to not tame her - I have had her saunter right over to me in the basement and stand in front of me looking straight up at me! They tame down very easily.
Keep this little one!
