I'm in the process of doing halogen to OEM LED, which is basically the same, and I'll do a writeup when it's done (prob within a couple months).

But the reason that no one does it is because it's super complicated. You need to run two hot wires from the rear fusebox to the headlights, the pinout to the headlight assemblies changes on both the headlight and the ECU side, you need to run more cables for a new CANBUS, you'll almost certainly need a new FRM, and then you have to code the car.
