Sorbet with a Reduced Sugar Simple Syrup - Will it work?

Hi Chowhounds - I have a gorgeous 30 lb watermelon in my kitchen. I was thinking of making a simple sorbet that I found on epicurious. The recipe calls for 8 cups of cubed watermelon, 1 cup of "simple syrup" and 2 tbs of lemon juice. The "simple syrup recipe" calls for 2 cups of sugar dissolved in 2 cups of water. Because the watermelon is plenty sweet and because I want to reduce my refined sugar intake, I was thinking of making a "simple syrup" of 2 cups water and 1 cup sugar, and use one cup of this concoction for the sorbet recipe. Will this work? Will the sorbet still have a good consistency? A search on this board reveals only recipes and not a thread on reduced sugar sorbets. Thanks Chowhounds!
