[Q] Is it possible to add these moto x features? topic

Moto display, the nexus version seems inferior to what the moto x has.
I'd like to be able to have moto actions too so that I see my notifications with a wave of my hand.

Moto Voice, on the moto x it's always on (even when the screen is off) and you can change the phrase from ok Google

And double twist to start the Camera


Also I'm coming from a locked BL Samsung so I'm used to features and lag, which nexus 6 rom has the most features?
