Could we make it where Shaco evilly giggles when he is nearby invisible?

For someone who has an openly available ability to stealth, can we get a better way to know when we are bout to get ganked by this clown? OTHER than wards, since he can also blink around the bush from the tower entry ways.

Eve has a limit to how close she can get, Rengar has Exclamation marks and Kha's isn't as long as a duration, since he has to become visible between uses. It's annoying to be straight forced to use a flash because he appeared right behind you with his slow and fear combo.
