Never abandon your thoughts it gets lonely without them! I have a pre-refresh but assuming the area you have circled is designed for the aero air curtain for reducing drag, increased fuel economy ect. I don’t know how much room is behind that area or how easy the access. Doubt aftermarket would place something there so modification of the plastic grill screen as well as brackets for mounting the actual lights would be needed.
With the right ingenuity it could be done and would be something like the 19-22 sierras which have the OEM fog lights in a similar location.
