Yes, that's what I had in mind. it's simple to patch those two functions for 
this purpose, without changing behaviour with a layout that contains bin/. 
Especially for dbus it makes sense to me to have that upstream. The key can 
than also be used by other projects to find existing dbus installations and 
avoid having multiple dbus versions installed.
Would you accept such a patch to windbus in case it allows KDE on Windows to 
continue working as before? (An alternative, which I dislike though: Assume 
$INSTALLDIR/binary.exe/dll structure in case the $INSTALLDIR/bin/ check 
failed)

gpg4win won't depend on KDE on windows directly nor vice versa, from the KDE 
point of view gpg4win2 is rather an alternative, heavily stripped down KDE 
distribution (i..e. only Kleopatra, necessary parts of kdelibs, KDE icons, 
gnupg libraries and dependencies (Qt, dbus...)).
