The trick would be making ones for the 06+ because they are sealed housings and you can't just bake them off of each other like the '05. We are running into the same issue because we are trying to redesign them as well. We are even looking at manufacturing the clear plastic cover but that is getting really technical.
And, Yes the '11s do but they are a different design and you'd have to modify your clam. The LED's follow the bottom edge and up the rear. I Love the design but dont know how it'd look with the symetrical lenses. 3/4 angel eyes do look really good on them and give it more of an aggressive look. But with the newer cars you still have the sealed lens issue.
Eglinlotus, another thing to help that we are considering is refabricating the rear plastic housing. Then, we can cut out the old housing, throw it away then reglue the new one in once we've modified it. Mold making for the plastics is not too bad but would only suggest it if you plan to manufacture 10+ for sale.
If you decide to take this one we'd love to help you figure out how to do it, so if you have any questions just PM me. We've been doing custom parts for a long time and love new challenges.
