Yes, they would. I called and asked this as research for a paper I was writing in school a few years ago. I pretended my 5 year old son loved Cinderella and enjoyed dressing like her. I asked if he would be permitted to get a princess makeover at the BBB. At first the cast member suggested the night package. When I turned this down, and said he really would prefer to be a princess, she put me on hold and "checked with a supervisor." She came back on the line and said, yes it would be fine and we could choose the package we wanted when we arrived, based on what would work best with his hair.
