No, you can't do this without swapping all other electronics and control modules in the vehicle. The reason is the communication with the vehicle and the steering rack that takes place. Referred to as the vehicle architecture "Powernet". Electric power steering racks rely on the CAN communication from the vehicle that your 2012 is not setup to send, specifically the signals to the electric steering gear.
Honestly the early iterations of power steering really aren't that much better from a steering feel than hydraulic. We haven't really benefitted from electric power steering until recently like on the 5th gens when they have been able to implement things like lane keep assist or wheel disturbance rejection.
