Brian,
Wondered when you'd get going on this...

As we all know, fairings are...challenging on this bike; perhaps why Mother Honda never went down this path... The radiator cowls are so massive, and the relation of the front tank bottom being raised above the bottom triple tree clamp, and the non-standard headlight makes fitment, let alone aerodynamics difficult.
IMHO (and just like anuses (ani?) , everybody has one....

) , I think your fairing would look more... conventional, if it could be lowered. When I resurrected the "other" Batwing thread, I kind of changed direction because the Legacy Valk Interstate Fairing fit so well; but the thing that enabled it to work was cutting the cowls down, and eliminating the space-helmet based, dimensional-challenging headlight.
Still on that project , and will post an update in the other thread later. But you might consider cutting the cowls down. I finally received the HD Batwing yesterday that I ordered a few week ago, and taped it onto the bike - remember, this is the direction I wanted to go before I got...distracted with the Interstate Fairing.

It actually is much closer in the mock-up than the Interstate Fairing - primarily because it is almost half the width at the headlight.
Same style as yours, but the difference is that the shrunk and lowered cowls allow the lowered fairing position; it looks more ...conventional. It would still need some work, as it STILL interferes with the cowl on full lock - but it would need a lot less trimming than the Interstate Fairing.
In the Photoshopped Batwing pic in the other thread, the fairing opening is enlarged to fit around the stock headlight. Might work, but Photoshop stuff in 2D is easy; shaping 3D ABS is a little trickier; alternatively, a stock HD headlight (which is also available in LED) would literally bolt right up to the fairing.
I really think that if Honda had devoted one guy to this 5 years ago (along with porting over Interstate Saddlebags, and a reasonable sized luggage rack), this problem could have been solved at the factory. The Valk would have been way more popular, they would have sold a boatload, and they would still be being made... Instead we have 3, no, now that Bill has gone another direction (

) , 2 guys trying to solve this in our garages; or on the patio...

Note that while the cowlectomy appears radical, it was actually pretty easy in execution. And it's an almost have-to for a fairing project. You cannot get the fairing low enough because the cowls are so high. Spoke to a friend who does my major steel welding (as well as ABS fab), and he assured me that getting the cowls from what I have to what I need is not a problem. Even if the Interstate Fairing does not work out, the (conventional) Batwing mounting will still be much easier with the cowlectomy.
Someone should make mini-cowls in fiberglass. Hmmm....
My $0.02...or maybe a bit more.
