I guess I'm not really clear on what you're asking for - you want a method to turn the screen OFF without using the Power button, or you want a method to turn the screen ON without using the Power button?
If the former, just set a very short timeout for the screen; if the latter, just use the fingerprint sensor to wake the device.
I don't understand what a special lock screen app has to do with either of the scenarios that I listed.
