Fully agreed, i even had considered something like that triggered by a similar idea from a DIY velomobile in my neighbourhood. With one exception: the shape of the back of that VM is pretty complicated as You can clearly see below (i thought it could be seen in the pics shown previously). The difficulty is always to integrate the lowest part of the body.
The other issue that lets me hesitate is that i am unsure to which degree it will be possible to stiffen the back. As far as i can tell there are also issues with the stiffness of the body near the joint og the rear fork. With some significant variation between each individual GoOne 3. Mine seem sto belong to the weaker ones. So the outcome of my efforts to improve the fork is uncertain.

I built my custom design out of coroplast in the kitchen of a former apartment I lived at. There was minimal mess. Working in a tight space was not easy, but it was doable.

I'm aware of that. I do actually have the possibilities to work with wood, and know what to avoid (sanding) and what to to instead (scraping)

Get a basic frame design for the tail down that you know will work after testing it,THEN build the tail around it.

That's actually whai i did, but sometimes You notice problems not unless You are driving hard. Which is waht has happened. And that carboard fairing was never intended to be more than a 1st attempt which cost me a just 2 Euros. The tail has definitely been made just for testing and getting experience with as little investment as possible.
For a final solution there remains actually a lot more to test: how much can i reduce weight? And: use relatively cheap material for the fairing. The paulowna wood is not too expensive, and it will allow me to proctice "stich and glue" / lute buildin techniques.

Stiffening the rear of the frame is always going to be needed, given how much bicycle parts like to flex.

But it'll still take a few weeks until its getting warmer again for doing any structural work on the bike itself.

BTW: the available parking space limits the length of the tail pretty strict.
