Looking at photos of the Bali version, the 4 patch unit that joins the rings is very pointed at the corners. Most traditional DWR patterns have a 4 patch with 90 degree corners. Also, based on the templates that I have, the melon section is very narrow. Not sure if there's enough room for the star point to be appliqued there and have enough of the background fabric showing to emphasize this piece. Having said this, I think it's an intriguing idea and I would suggest you make a sample block or two. I'm guessing that you will not be able to combine the 2 patterns, you would have to draft your own star points to fit in your melon template. If you do decide to proceed, please post a photo!
