I definitely think they should do this. And no, I don't think this would be an "easy" counter. Currently supports are used to other spells like exhaust or flash which help a ton in the laning phase. You would need to sacrifice one of them to pick CV, possibly making your lane much harder. This is called decision making. But currently almost no one makes that decision because CV just doesn't give enough. This feature could tip the scales.

There are so many ways in which they could balance this to be just right. They can increase the cooldown (considering that you could start clearing wards with it), they could make the reveal range lower than the sight range (so to get the reveal effect you would need to actually target CV properly), the reveal could also have a shorter duration than the sight (like 2-3 seconds if you hit a champ with it, its enough to bring utility).
