In a large saucepan, melt butter over medium-high heat. Add onion; cook for 1 minute. Add rice and garlic; cook for 1 minute. Stir in broth and salt; bring to a boil. Reduce heat to medium-low. Cover and simmer until liquid is absorbed and rice is tender, about 15 minutes. Remove from heat. Gently stir in 2 cups Creamed Corn, 1⁄2 cup Cheddar, 1⁄2 cup Monterey Jack, cilantro, chile powder, and cumin.
Preheat oven to 350°. Cut bell peppers in half lengthwise, discarding seeds and membranes. Place peppers, cut side up, in a microwave-safe 13x9-inch baking dish. Add 2 tablespoons water to dish. Lightly cover with wax paper. Microwave until peppers begin to soften, about 3 minutes. Drain any excess liquid. Fill peppers, mounding rice mixture in each pepper half. Drizzle with oil. Cover with foil.
Bake until tender and heated through, about 35 minutes. Uncover; sprinkle with remaining 1⁄2 cup Cheddar and remaining 1⁄2 cup Monterey Jack. Bake until cheese melts, about 10 minutes more.
