Small Rework Idea for Draven

Hey, I just had a suggestion for a mini rework on Draven. So Draven is an executioner but has no execute in his kit. I was thinking make his Q a 2 part ability so from range he throws his axe like normal as is, but when he gets into melee range he slams his axes into the opponent dealing bonus damage and extra damage based off of % missing health. This would work well with his high risk high reward kit and makes sense that the champion would be played that way, aggressively. I think it would make for some cool flashy plays and add another element into his kit which would make him seem cooler and make some sense as well. Maybe even make it so when he flashes in and hits his axes into the enemy he consumes his axes would make it more balanced as in you need to know if it will work or you risk losing your axes.
