Default [Q] Double-tap wake functionality on non-sense ROM

I'm currently running CM11 nighties on my M8.

I know that other phones have had tap/swipe to wake enabled through kernel modifications. I've searched through the forums but haven't found anyone discussing ways to restore this feature that's pretty useful because of the awkward placement of the power button and the size of the phone.

Is there a kernel/xposed module/something that would restore this feature? Something like Bulletproof ( for the m7?
