Possible Teemo Blind change

I was thinking of a way to to change it was make it have a charge system. So you can have say 2 charges max at level 1 blind and maybe 3 at max. I think the charges will some what punish him early game blowing mana and double cool down timers being greedy because of charge system. I also think the charge system will add a new safety to teemos lane pressure by being able to double blind for an escape if he stacked his charges. this can also make teemo more useful in team fights. so i feel like it has some small con trade offs early but over all makes teemo more healthy in this team fight meta and safe to play.
