In a large skillet, cook four strips of bacon for the burger over medium high heat. Remove to paper towels to drain. Season the burger patties with salt and pepper and add to warm bacon drippings. Cook, turning once, until burgers are cooked to desired doneness. Turn the heat off; place cheese slices on top of burgers and one strip of the cooked bacon on top of each slice of cheese. Cover to allow the cheese to melt.
Heat a second large skillet over medium heat. Add 4 strips of bacon, chopped, and cook until crispy. Melt in butter, then add jalapeno and red onion to the skillet. Cook until the onion is softened, then add garlic and cook and stir for 30 seconds. Add the corn and continue to cook until corn is just tender, about 2-3 minutes. Stir in maple syrup and 1/2 tsp salt and remove the skillet from the heat.
Mash avocado flesh with lemon juice and 1/4 tsp salt. Add in the mayonnaise. Spread the mixture equally on the bottom of each bun. Top each bun with a cheeseburger patty and sweet corn relish.
