ADC Heimerdinger

What would you think about adding some marksmen ratios to Heimer's turrets? Such as adding an AD ratio as well as attack speed, this will allow his the laser to fire of more frequently which would apply on hit effects more often. I don't mean this as a buff for him but instead a way to make him more unique. Also letting him proc black cleaver with his lasers will shred any tanks that try to wade in. Heimerdimger should be a fortress that claims a piece of land inside his turrets but if he ever leaves them he's extremely vulnerable.
