To clarify what I said. Cost effective: leave the stock screen alone. In my case I have a short screen I use for summer, and a stock one for touring, etc. So I want to keep the headlight unit self contained. This is cheaper than getting custom screen. Because the 60mm high beam is very long, it's two deep to use the 60mm for high and low beam. Look: Having said the above, it is possible to have the much lower profile 90mm high beam along with a 60mm low beam. But to me, it does not look as good. Also the two lamps would use different bulbs which is less convenient on the road. Now that I have a set of acrylic lenses to maintain the twin 90mm look, it's possible to put whatever light you want in the back. You can put a square squadron led as high beam, or the 60mm low beam on the bottom. It wouldn't destroy the look. Hope this helps.
