Handling and loading become squirrelly quickly when you have a high center of gravity.
Rather than a standard diamond frame maybe consider a Worksman trike for your frame.

They are under three hundred dollars.

Also since this is going to be a hard working utility vehicle, a stout undercarriage like the Worksman will be highly desirable.
I recommend using the NuVinci as a transmission.
No, I don't think it will be a problem. The fairing or box is mounted to the head-tube, so it is frame mounted. It does not turn with the handlebars.
The existing design has proved very sturdy. The weight of the load *improves* the handling, IMHO. It is easy to ride with no-hands when the box is loaded.
