New Idea for RGMQ

Just had a thought, what if like in Hearthstone's Tavern Brawl where you earn a free Classic Card Pack, your first game in the RGMQ each week netted you an additional Hextech Chest, 1, 2, or 3 Key Fragments, or additional IP? I feel like this could draw people in to try the modes that they would otherwise never play, and maybe they would be surprised with some of them! Thoughts?
