New Adc concept

I was thinking...there should be an adc who has mechanics similar to rumble by the overheating feature. This adc would have a cannon by his side and every 5 abilities (changeable) would cause him to reload or something. He wouldnt use mana but gunpowder instead and he could have special items specifically designed for him like the original rengar bonetooth necklaces. Passive: Reload after every 5+ abilities and slower movement speed but (+7.5% AD) per basic attack Q: a more powerful cannonball (+75) (+ 0.7 AD)(0.3 AP) that knocks the adc back-similar to caitlyn W: Chain shot that slows 65-80% for 2.5 secs+ adds 35% attack speed for 4 seconds E: Grapeshot-similar to grave's but there is no in-between Shots blind enemies hit for 2 seconds R: Human Cannonball-loads himself into the cannon and maye hurls himself at enemy champs. He would then turn into a slow melee champ until he returns to his cannon (changeable) or Global ult That just shoots a giant cannon 250/ 375/ 500 (+ 0.85 AD) (+50% AP) honestly, i believe this would be an awesome champ to play. he would look like a pirate maybe and a possible skin can be a circus cannoneer please support
