Make Gangplanks Ult Proc Barrels

I'm not a hardcore Gangplank main, only level 4, but I think it'd be cool if his ult caused his barrels to take 1 damage with every wave, or even one shot them, because as it is Gangplank has a 49.3% winrate (not too bad but not too good) and doesn't bring much to a teamfight unless played really well and places his ult well. I know his barrels do damage based of how much damage his auto/q did but they could easily just make it do 1:1 of his attack damage and still have a chance of critting. This may make him OP or super strong but it's just an idea! Cannons! No hate pls
