What if invisible champs could see each other?

oh like how in Dragon Ball, if 2 people use instant transmission they can see eachother at normal speed

So, if I'm taking a bath, everyone else in the world who is taking a bath can see me too? If I'm knocking on someones door, anyone else who is knocking on someones door can see me too? If I'm sitting in a chair, anyone else who is sitting in a chair can see me too? If I'm hiding in a pitch black room, anyone else who is hiding in a pitch black room can see me too? If I'm drinking water, anyone else who is drinking water can see me too?

Um... considering how invisibility works... no... Maybe on some champions, I guess, and we could differentiate "stealth" from "invisibility."

Sounds like I would be spamming teemo to become a stealthy pink ward for my team :D
