I'm in the same dilemma but have learned to deal with it. You could buy a new headlight housing which is around $170 from courtesy parts. You could find someone with the same problem and trade with them (like me

). Or you could try to take apart the housing and clean it up a bit. Changing to a kouki front would just be a burden with the cost of new headlights, fenders, and whatever else you need. Stay zenki, it looks better.
