Scoop out inside of each potato wedge. Place wedges on a large, lightly greased baking sheet.
In a small bowl, combine chicken, sour cream, cream cheese, and hot sauce and mix thoroughly.
Divide mixture evenly among potato skins.
Bake at 350 degrees 10 minutes.
Remove wedges from oven; sprinkle each with 2 tsp. shredded cheddar cheese and top with a sprinkle of blue cheese.
Bake an additional 2-3 minutes or until cheese is melted.
