Combine blueberries, whiskey, and sugar in small saucepan. Bring to a boil; reduce heat to low. Simmer, uncovered 10 to 12 minutes or until berries burst, stirring frequently. Stir together water and corn starch; stir into blueberry mixture. Cook and stir 1 minute or until thickened; remove from heat.

Sprinkle bacon slices with 1 tablespoon brown sugar bourbon seasoning. Cook bacon in medium skillet over medium heat 12 to 14 minutes or until crisp. Transfer bacon to paper towels to drain.

Preheat charcoal or gas grill with greased grill rack for direct cooking over medium-high heat (375°).

Sprinkle both sides of burgers with remaining 2 tablespoons brown sugar bourbon seasoning. Grill 10 minutes, turning halfway through. Top with cheese and grill 1 to 2 minutes more or until cheese is melted and burgers reach 165°. Remove from grill; loosely cover with foil to keep warm. Grill buns, cut sides down, 30 to 60 seconds or until lightly toasted. Remove from grill.

To serve, top bun bottoms with burgers, candied bacon, red onion, arugula, and blueberry-whiskey mixture. Lightly season with black pepper, if desired. Place bun tops on burgers.
