I love the look of the 1LE. And yes it steals some of its looks from the ZL1.
I put an SLP Slitter and ZL1 side skirts on my car because I really like the look.
But I don't want my car to look too much like the ZL1. For that reason, I would not put the ZL1 front end on my car. And I also like the way the front end looks on the Camaro SS.
Here's a pic of my car with the SLP Splitter and ZL1 side skirts.
