Yes, and in fact that's how we ship things in Fedora (KDM being a special case
because it doesn't use KConfig). The KConfig search path in Fedora is:
1. ~/.kde/share/config/ – user settings
2. /etc/kde/ – systemwide settings
3. /usr/share/kde-settings/kde-profile/default/share/config/ – Fedora kde-settings
4. /usr/share/config/ – upstream shipped settings

The way we implement this is that:

* to implement 3, we ship an /etc/kde4rc (and kderc for legacy kdelibs3 apps)
  with the following settings:

[Directories]
kioskAdmin=root:
profileDirsPrefix=/usr/share/kde-settings/kde-profile/

[Directories-default]
prefixes=/usr/share/kde-settings/kde-profile/default/

* to implement 2, we ship a patch to kdelibs:
http://pkgs.fedoraproject.org/cgit/kdelibs.git/tree/kdelibs-4.6.90-kstandarddirs.patch
(second hunk, the first one is one of the changes required to make
LIBEXEC_INSTALL_DIR=/usr/libexec/kde4 work properly)
The patch is required because we need this to have priority over profiles,
which isn't supported in the upstream kdelibs code.

I think the setup we use in Fedora is optimal (and actually I wish all
configuration systems would work that way, not just KConfig ;-) ).
