There would literally be no point. Dragon fruit adds very little flavor to the smoothie -BUT you can't beat red-fleshed dragon fruit for its lovely vibrant color. There are two colors of dragon fruit: white-fleshed dragon fruit, which is actually a creamy white color, or red-fleshed dragon fruit. Because of its flavorless flesh, there is really no point in making a dragon fruit smoothie if you aren't going to use the red-fleshed variety. Just make a berry banana smoothie instead!
