Weird how you only mention that after an example broke the version you wrote in your OP. 
Retconning your idea after I pointed out how easily it breaks doesn’t mean I didn’t break it, champ.
It doesn’t matter what I have to say about it, though. Mike already said this doesn’t work, had you bothered to read what @Heavy quoted to you:
You’re proposing an intensely obvious idea. They thought of it already. Time for you to throw in the towel.
