Gangplank Rework

So I know you guys are currently working on a rework for GP, and I wouldn't consider myself an expert in champion design in the least, but I know I read somewhere that it was for possible thematic reasons. I don't really have an entire kit to offer, but I was thinking of a passive that is really thematically fitting for him, and just had to get it out of my head.

Gangplanks next autoattack is ranged and will hit for 125% of his total AD and apply on hit effects. It would also apply The current slow and DOT from Grog Soaked blade, but his regular autos wouldn't. The cooldown (Im no expert at times) could be like 8 seconds, and oit would be halved when standing still (Because its easier to reload a flintlock while standing still) I just thematically like this idea because he is hacking and slashing and using his pistol, and reloading. IDK just thought I'd get it out there
