I imagine the maple would do that hot sugar thing in the grill and enhance the maillard reaction. IF those are low bush blueberries, their acidity and tartness could add a lot to the meat with a backbone of sweetness. But they're probably high bush, and just add a bunch of sweetness with a very mild blueberry flavor.
What could this possibly taste like other than a tart burger?

Interesting, I had no idea bluberries could be complex 😅
