Yup, I would all day long as long as you have a system in place. Take them through the line and then use the chicken exit, and then have them wait in the gift shop or near a cast member for the 3 minutes you'll be gone, and make sure she knows that cast members are the people she goes to if she has any trouble, and doesn't talk to anyone else. After all, this world is a cruel place, but this is WDW, not a street corner at night
