Pumpkin Cream cheese dip

Go here to see this great recipe and a picture. I think I could make this into a fat free/sugar free treat. What do you all think?

Pumpkin Cream Cheese Dip

8 ounces cream cheese, softened
1 15-oz. can pumpkin
3 cups powdered sugar
1 tsp cinnamon
1/2 tsp salt
1/2 tsp ground ginger
1/4 tsp ground cloves

We could use fat free cream cheese and use splenda (blender to powder sugar).
