melee adc's

Is there some way we can make melee adc's a thing, yasuo is a good example of a champion who can be a melee adc, or master yi.The only reason i believe this cant be done at the moment is cause there is no disadvantages to being a ranged compared to a melee. A ranged champion will always be more likely to win lane or do the most dps simply cause they have the range to do so and the fact there are no penalties.

Some ideas i propose that can help balance this out are .Ranged champions should have longer attack animations this way kiting is a lot harder , kind of like thresh's aa .Ranged champions get less attack speed, lifesteal, or critical strike percent and damage from items .implement dodge or evasion items back in League giving melee's a higher percent then ranged, but make it unique so it cant be stacked
