Spread caramel dessert topping evenly in bottom of crust. Set aside.
Pour half-and-half into large bowl. Add pudding mixes, ginger and cinnamon; beat with wire whisk 2 minutes or until well blended. (Mixture will be thick.) Let stand 5 minutes. Gently stir in 1 1/2 cups of the whipped topping. Spoon into crust.
Refrigerate 3 hours or overnight until set. Spread remaining whipped topping over filling just before serving. Sprinkle almonds around edge of pie. Store leftover pie in the refrigerator.
