Heat grill to medium.
Whisk together the cream cheese and goat cheese in a medium bowl until smooth. Fold in the Cheddar, corn and green onions and season with salt and pepper. Fill each jalapeno half with about 2 tablespoons of the mixture and sprinkle the top with some of the ancho powder.
Place on the grill, filling-side up and cook until slightly charred and tender, about 7 to 8 minutes. Spoon the red pepper sauce onto a platter and top with the jalapenos.
Combine the pepper, tomatoes, vinegar, honey and cilantro in a food processor and process until smooth. With the motor running, slowly add oil and season with salt and pepper.
