We are already doing such a project but more game based rather than faucet based.
You can see the thread here:

One thing I want to point out is that the earning examples you show in your post are maximum possible revenues and do not exactly work out the same with different countries and time zone. Actual Mobile revenue is much less as compared to what is advertised.
Also the video ad is not available always around after a person watches 5 to 6 videos there would be no more videos for him to watch.
Hope that helps you to increase your viewpoint towards this.
