Yes, the two boxes are as far forward as I can get them. The back of the fairing is about 24" wide so the saddlebags protrude about 2" more on each side. My legs are sticking out there as well. Some type of gaiter to move airflow outboard?

I can see why you want to change the saddlebags. What's inside? If it's a single battery, that's a problem. If they were packed with Tesla 18650 cells, then you could curve at least the outward face.
I'm using Enerdels and each side has two assemblies of six "elements." They're not that granular. They are butting up as close to the side of the bike as I can get them. They could be a *bit* lower but that would compromise ground clearance.

I don't understand "rotating them to horizontal"?

You get to choose from the first two.
I'll have to think about this! I always thought I'd have to end up with some sort of Kamm tail. I don't understand fineness ratio, have to study...
