Heat oven to 400°F. Line a large baking sheet with foil and set a rack on top.
Halve the jalapenos lengthwise and scoop out seeds and membranes. Wear gloves if needed.
Stir cream cheese, sour cream, cheddar, chicken, green onion, garlic powder, onion powder, smoked paprika, salt, pepper, lime juice, and cilantro in a bowl until smooth.
Fold in half of the crumbled bacon. Adjust seasoning to taste.
Fill each jalapeno half with a heaping spoonful of the chicken mixture and place on the rack.
Toss panko with olive oil. Sprinkle over the stuffed jalapenos, then top with remaining bacon.
Bake until the tops are golden and jalapenos are tender, 16 to 18 minutes. Rest 5 minutes.
Garnish with extra cilantro and serve warm with lime wedges if you like.
