Rather than starting from the bigger red shape as the front of the trailer.
Within the 4' of towbar , some blunt nose could be used .

I have looked at a variety of ideas, but think the eliptical profile, if possible would be the best way to go for the entire trailer canopy.
Through it's inherent shape it would be the strongest/lightest structure and would also be more generic to a range of vehicles, I would also have a rounded nose on it to help close the gap to vehicle.

How about a half-rounded trailer with blisters right behind the orange area. Something larger than a running light but smaller than an aircraft canopy. To offer something for the air to reattach to.

Sorry rambling is a bit confusing, in actuality I am looking at both, to make trailer canopy as generic as possible using eliptical profile for reasons mentioned above and then also look at what needs to be done to trailer/vehicle/gap to smooth the transition from one shape to the other.
I like your idea for the corner transition on trailer, as it will have a double life as utility and camper, that would be an ideal location to mount some skylights, if one could find domed teardrop units they would be perfect for the position.
Another thing I was looking at is using deflectors or aero fences on vehicle to guide airflow into the corner void in such a way to increase pressure there and minimise resk of vorticies.
