Or does the cap in general constitute a Kammback and maybe add nothing.

It was just a thought and wouldn't be all that hard to add if I would see any more benefit. Or if the benefit is too small maybe it's not worth doing?
The base pressure of your wake will be determined by the separation line ahead of the green line area,so it can't really increase the pressure,but it can help sculpt the wake a bit and it is occupying volume,so it must be beneficial.
