In the work bowl of a food processor or the container of an electric blender, place tomatoes and 1⁄2 cup tomato juice; pulse until coarsely pureed. Add cucumber, bell peppers, and onion; pulse until finely chopped. Pour into a large pitcher; stir in remaining tomato juice, 4 tablespoons lime juice, Worcestershire sauce, and celery salt. Stir in vodka. Season with salt and hot sauce to taste. Cover and refrigerate at least 4 hours, or until chilled.
