you could add BBQ sauce to a recipe... I'd be careful not to go over board with it and cut down or eliminate any water in the recipe. i guess for potential issues, ones that are tangy are likely tangy from vinegar which could hurt binding. if it were me, i think i'd try to recreate the tastes of a bbq sauce i like with spices and add encapsulated citric acid for tang... brown sugar, mustard powder, ketchup powder (i have no idea how close to ketchup it tastes but it's supposedly very close),..
