If you're looking for something along those same lines, and looking for a kit, Austin Homebrew Supply has a Honey Hibiscus Wit or a Lemongrass Wheat. I've personally never tried the honey hibiscus wit, but it seems to get good reviews. The lemongrass wheat I have tried, and it's pretty darn good for a summer beer.
If you're looking for something non-kit, check out the recipe section! There's a whole category for fruit beer
Edit: got beat to it XD
