Place wafers in pie pan, arrange to make a shell. Crumble a few in center or around to fill in spots. Layer sliced bananas and blueberries over crust. In a separate bowl, beat cream cheese until creamy. In another bowl, beat eggs well, butter, flavoring and milk. Beat well. Place mixture in a saucepan and cook on low, slow, stirring constantly for creaminess. Cook until thick and remove. Let cool. Add beaten cream cheese and whipped cream. Pour a layer of pie mix over fruit and wafers. Place a second layer of sliced bananas and berries, then add a layer of pie mix.
Chill and serve.
You can add some berries on top center or the edges for decoration.
