Ohmwrecker

I was thinking about ways Ohmwrecker could be more useful and relevant, and I thought of something quite interesting. The active on Ohmwrecker, the one that disables towers, could be quite useful on a stopwatchesque cheaper item that builds into Ohmwrecker. If it were to come with say, a 3 minute cooldown, I can see this more basic item being quite relevant to the game. It may even bring back several diver champs that have been forgotten for quite some time. I'm not sure how the balancing would go, but I was thinking maybe 1250 gold?
