Puree raspberries with syrup in blender. Strain puree into medium bowl; discard seeds. Cover; chill. (Can be made 2 days ahead. Keep chilled.)

Add 1/4 cup powdered sugar; beat until stiff but not dry. Using same beaters, beat cream and remaining 3/4 cup powdered sugar in large bowl until peaks form. Fold in lemon peel and cinnamon. Fold large spoonful of cream mixture into whites, then fold whites back into cream in 2 additions. Fold in 3/4 cup amaretti. Transfer mixture to prepared pan. Cover with plastic wrap overhang, then foil. Freeze at least 4 hours. (Can be made 2 days ahead. Keep frozen.)
