This happened in two steps:
1) When I had the front fascia off for the intended WeaponX coolers, I swapped out the front grill, splitter & bezels (don't need fenders or wiring harness and the ZL1 fascia works). You do need some clips # 11547341. I got them in 10packs from LB Auto Parts, much cheaper than individually from the dealer.
2) Later I added the canards/dive planes
NOTE that I did not change the upper grill, you have to look real close to see the difference.
The comparison pictures are from Badmojo, he did the conversion before me.
Super long thread on the conversion here:

I'm not super keen on the look of the canards and planned to only put in the ZLE bezels for the larger opening and "assumed" better airflow. Once installed, they looked unfinished, so I installed the canards.
