Slice each cake widthwise into eight slices; set aside. Place bananas and orange juice in a bowl; gently stir to coat. In a large bowl, beat cream cheese and sugar until smooth. Add the pineapple, milk and pudding mix; beat on low speed until blended. Fold in 1-1/2 cups whipped topping.
Line bottom and sides of a 4-qt. glass trifle bowl with half of the cake slices. Arrange a third of the banana slices and strawberries against the sides of bowl. Carefully spoon half of the pudding mixture into the bowl. Arrange half of the remaining bananas and strawberries around bowl. Add the remaining cake, bananas, strawberries and pudding in the center of bowl.
Cover and refrigerate for 4 hours or overnight. Before serving, spread with remaining whipped topping. Garnish with additional bananas and strawberries and mint if desired.
