The quickset 912 comes in either Z wave or zigbee in brass, so it should match your 914. If you have room on the interior side for both control boxes. 
But it ends up being a sort of fortressy look with two keypads on the outside.
I think most people who want a smart lock on both the deadbolt and the lever do one of the following:
- buy a device designed for exactly this purpose, with a single keypad that unlocks both the deadbolt and the lever lock. That won’t fit all use cases, but it’s a nice look and works for many people. Yale makes a zwave model of this type. Assure YRC226
- get one of the retrofit models for the deadbolt where you don’t see any extra hardware on the exterior side of the door, there’s just a knob turner on the inside. That way the outside lock for the deadbolt looks like it always did.
Then get any smart lever handle lock that you want for the exterior. You just have to measure everything to make sure it will fit vertically on the interior side. This will also give you only one keypad on the outside so it looks quite nice. And it gives you added security if you want it because the two locks can be controlled separately. Yale, Kwikset, and Schlage all offers zwave lever locks in multiple styles.
- A less popular but still feasible option is to add an electric strike for the lever handle. This requires a lot more wiring, but it’s the way you set up the door if you want to be able to physically open it with a door opener, like for someone in a wheelchair. Here’s one project report.
