You end up with not only a 'smaller' wake, but a wake of higher base pressure, the goal of streamlining.
It's not as 'good' as a proper boat-tail, but it gets you 'towards' the performance, with less material, a lighter structure, and a few orders of magnitude easier to fabricate. All the reasons for Trailer Tail.
So, you are suggesting this?

That would be better ..yes?
