People have successfully swapped in a Model 3/Y wheel and colckspring (module with the stalks). They mechanically fit identically to the current S/X parts, but you do need a microcontroller board to do CAN spoofing. The S3XY button people claim they are working on a commercial version of this swap.
I have not heard of anybody swapping in a previous-generation S/X stalk assembly and wheel though. That might be a lot tougher since the refreshed S/X essentially switched over to modified 3/Y parts-bin components all throughout the car.
