Light brown sugar, dark would be good too.
Candied ginger should work. Add anything to your own liking. Changing a recipe is a sign of a good cook. I really like fresh ginger, it makes a great tea too all by itself (with a little sugar and milk).
Pumpkin pie spice alone should do it but I've always added the strait spices too.
