If you want to cut out all the sugar fully from this oatmeal cookie recipe, then you can use all maple syrup instead.By doing so, you will need to increase the flour amount - so, replace the sugar with an additional 1/2 cup of maple syrup (1 cup total), and up the flour to 2 1/2 cups of flour total.
