Fog/driving lights behind grill??

[79apache]

Has anyone installed fog or driving lights behind a stock grill?
How did it work? Meaning, was the light output reduced or shaded much? I do not wish to cut my stock grill
I thought this might make for a cleaner install but it will take a little bit of doing and I thought I would ask first before putting a bit of work into something that may not work well.
Thanks!
