Caves and Cliffs Mob Idea: The Looker

Now I don't know how the Deep Dark is mainly going to work. However, I do have a idea for a mob that acts as a "henchmen" to the Warden. The Looker is a mob that is essentially a more nimble and skinny Warden, it has had some experience with sunlight, so it was able to develop eyes. As you traverse the Deep Dark there will be a few of these lookers scouting around the area. Once spotting you, it will first send a signal to the skulk sensors, and if the Warden is close enough, it will pick up the signal and come straight for you. One way to make this fair is if the Looker has some sort of cool down where you could get away in time. This mob would just drop a skulk sensor as it is not hard to kill him. Kill more, less worried you have to be of the Warden coming and having a not-so-friendly surprise.

I already explained the appearance, but here's it more in detail:
Has horns like the Warden
Has only white eyes, due to lack of sun
Long arms, short body, long legs

The Minecraft team is already working hard on the Caves and Cliffs update, so this idea I wouldn't expect to be added in, but just a idea!

Thanks!
