There are a lot more beer categories in real life than there are BJCP categories. Your recipe looks like an American Wit, which is not a recognized style, yet there are numerous examples of them, among them Leinenkugel Sunset Wheat, Shocktop, Blue Moon, and, as you noted, Sunshine Wheat. These basically are wits brewed with neutral yeast. Sorry that this doesn't help, but maybe the BJCP will recognize them.
