Preheat oven to 350 degrees F. Cook jumbo shells according to package directions. Using a large slotted spoon, transfer shells to a colander. Rinse with cold water; drain well. Set aside. In the same pan, cook tiny shells according to package directions; drain. Set aside.
Meanwhile, in a large saucepan combine Gruyere cheese, cheddar cheese, half-and-half, and pepper. Heat over medium-low heat until cheese melts and is smooth, stirring frequently. Stir in tiny shells.
Spread about 1/2 cup of the vodka sauce into the bottom of a 3-quart rectangular baking dish. Spoon the cheese mixture evenly into the drained jumbo shells; place stuffed shells in prepared baking dish. Top with remaining vodka sauce.
Cover and bake for 30 minutes. Uncover; sprinkle evenly with brick cheese. Bake, uncovered, about 15 minutes more or until heated through (160 degrees F). If desired, top with fresh basil.
