With the L322 grill you "should" be able to cut out all the plastic slats and then install the Saudi Grill Mesh and LR Badge.

 

I saw that L322 installed on a red D2 on instagram and it looked great. A nice, subtle facelift that also looks like it would pass a lot more air. I've been considering the same, and there are approximately 10 billion for sale on eBay, just haven't bit the bullet yet.
