I've done many, many things to break the warranty on that recipe, and most of them even turned out pretty good as long as you keep the honey proportion the same, use enough fruit to contribute some acidity, and use bread yeast. Some of the citrus hits were lemon-date and tangelo-vanilla, the grapefruit was OK but you have to really like grapefruit and it takes a year to be nice. My two best non-citrus JAO-based aberrations have been the ornamental crabapple and the blackberry... the ones I was least impressed with were unripe apple (blech), strawberry and black raspberry (didn't use enough fruit in either).
