I added a small hood scoop to mine, but it doesn't do much. Plan on going pretty tall if you want very much air. Mine helps a little, but it doesn't do a lot. Raising the windshield to let air under it helped a lot more.

If the master cylinder was empty (not the reservoir) it can be very hard to get all of the air out of it. It's the highest point in the system and can occasionally require bench bleeding before installing.
Before you work too hard at it, you need to find out if an 8-digit number will do you any good with your DMV. If they are wanting to be hard to work with, I bet they will try and insist that it have a standard 17-digit VIN.
Even if there is a number from DF it won’t qualify as a VIN. It would only be the chassis number. Typically the state supplies the VIN on these and mine is just a tag riveted to the frame.
I ran my pump with a relay based upon a random hot on ignition circuit. But then again I set up a mini fuse box to run the add-ons that rune off a relay.
I use T88 since it has a high strength and you can buy it in larger quantities with a long shelf life. But it turns out it can be susceptible to creep, although I haven’t had a problem with that I can identify.
JB Weld in the slow set version claims good creep properties compared to other...
You can do a quick internet search for epoxy creep. I didn’t know that was a thing, but I don’t know that it would apply here. It has a continuous load time component to it happening and I don’t know that applies here. Most of the load would be carried by the mechanical fasteners and the epoxy...
Looking on-line, you might be able to add a threaded insert although I would still probably use epoxy to help lock it in. It might be better than rivnuts. With rivnuts, you will have to be careful with getting the squeeze just right. You could also add more holes & fasteners, no matter which way...
So, 1/2 inch of something like a 3/8 bolt in carbon is all that is holding it? Be ready for the other side to fail. I'm surprised you haven't lost the entire thing. I assume this is some version of an eBay/Amazon wing?
Is it just threading into the carbon fiber or does it have metal inserts embedded?
If the carbon in thick enough, you might have luck with rivnuts. I've even used rivnuts with epoxy one or twice to add a little extra strength.
But if the wing doesn't have any way of accessing the inside to add...
