That happens not because kwebkitpart, actually kdewebkit, is incapable of
embedding nspluginviewer, but rather because there were multitude of problems
in doing so. Originally, handling of flash content was deffered to QtWebKit
because using nspluginviewer under kdewebkit/qtwebkit resulted many random
crashes and other nasty side effects. Nowadays though those issues mostly do
not exist and have been replaced by other equally annoying issues. For example,
clicking on links inside of a flash content does not currently work. Also there
seems to be trouble with resizing active or paused content on demand which
seems to cause crashes. 
That is why we purposefully blocking the use of nspluginviewer or whatever else
is configured to handle flash in KDE right now.

Right... the current nsplugin viewer included in QtWebKit is an in-process
viewer. There were/are plans to change it to out of process for the same
reasons you state here, but I have no idea what became of that goal.

That is because kwebkitpart tries hard to support, however KHTML specific they
may be, all of Konqueror's configuration and the nspluginviewer does not work
for reasons stated above...

BTW, since you seem to have compiled KDE from source, you can easily change 
kdewebkit to use KDE's preferred viewer for flash content by simply commenting
out the 2 lines below 

if (!excludedMimeType(mimeType))
    part = KMimeTypeTrader::createPartInstanceFromQuery<...>(...);

from "kdelibs/kdewebkit/kwebpluginfactory.cpp".
