I don't think that you can state that wake base pressure reflects body pressures at the end of the vehicle.
There are numerous pressure plots available of vehicles - some show similar pressure in the base area and trailing parts of the body, but many do not. The coloured pressure plots I posted above don't, and nor do the following:
I also had a good look through my reference library yesterday and could find nothing that supports the idea.
