The only problem with raising the windshield and adding a lower, separate slice of polycarbonate is what HD encountered with their old style windshields and that is bugs and crap will migrated between the 2 pieces of polycarbonate film at speed and park there necessitating removal for cleaning.
To each his own, but I don't care for the lip thing. The more layers you add between your line of vision and the road, the more opacity you have. That's apparent in your picture, the foggy look through the shield. Your second, lower sheet over the headlights isn't in your line of vision, the lip is. Having a clear line of sight 25 feet in front of the bike is about 1/100 of a second at 70 mph. Not even enough time for your brain to react to anything let alone activate your muscles to do anything about it.
I too, like the wood lowers. I'll pass on the top part.
