Prepare outdoor grill for direct grilling over medium heat. Cut 12-inch square sheet aluminum foil; fold up edges to create 1-inch rim, crimping corners to secure. Place bacon on foil and place on hot grill rack; cover and cook 6 minutes or until crisp, turning once. Transfer bacon to cutting board; blot both sides with paper towel and coarsely chop.
Brush both sides of baguette slices with oil; place on hot grill rack, cover and cook 3 minutes or until grill marks appear, turning once.
In medium bowl, toss blueberries, basil and syrup. Spread cheese on baguette slices; top with blueberry mixture and bacon. Makes 16 crostini.
