Question [Q] Other ways to turn on/off the screen without using the hardware button

I'm wondering if there's a way (app or manual edit of system files) to make the hardware buttons less used to keep them from getting soft

and for that I'm mainly focusing on the power button as it is frequently used, I have two ideas:
- taking the gesture from the new M8 which is by double tapping the screen, if you're a developer please tell me if it's possible to take that function from the M8 maybe edit it and make it work on the One Max!

- We have a great special thing called fingerprint scanner, and since it's not that good at identifying the owner's fingerprint but always works at identifying fingerprints of people, maybe we can use it to wake up screen by simply swiping the finger over it!

So here is my question and here are my ideas, if you have a good answer for me please share it in the comments!
Thanks XDA!
