Small amounts of carafa, roast barley, or black patent can give a boost to the color without much contribution to flavor. I'd go with the darkest one you can get, probably carafa special III, and use just enough to get the color you want. The flavor impact should be less than using crystal to get the same color, and it definitely will not add the sweetness you're getting from the crystal. There also are the new Blackprinz and Midnight Wheat malts available, but I haven't tried those.
