Blend the cream cheese and ricotta together in a mixing bowl.
Stir in the mozzarella, green onions, and parsley, and set aside.
Heat the butter in a saucepan over moderate heat and cook the flour for 3 to 4 minutes.
Stir in the milk and bring to a boil, stirring frequently.
Remove from the heat and stir in the oregano, salt, pepper, wine, shrimp, and crab meat.
Lay 3 noodles side by side in a 9×13-inch (23×33 cm) greased baking dish.
Top with one-third of the cream cheese mixture and one-third of the seafood sauce (it won’t cover completely).
Repeat twice and top with the parmesan cheese.
Bake uncovered in a preheated 350F (180C) oven until bubbly, about 45 minutes.
Let stand for 10 minutes before serving.
