It already does this, except the locale has to come first, i.e. 
/usr/lib/X11/fr/app-defaults/ etc.

The default search path for app-defaults (and similar) files is:


where %L is the full locale (e.g. "en_GB.utf8") and %l is just the
language part; %T is the type (e.g. "app-defaults"), %N is the
application's class name (e.g. "XTerm"), %C is a customisation value
(e.g. "-color") and %S is a suffix (not normally used).

The search path can be overriden through the XFILESEARCHPATH
environment variable.

See the XtResolvePathname(3) manual page for more details.

Note that the application will only use the first matching file, so if
there's one in the locale-specific directory, it will use that instead
of the one in app-defaults, not in addition to it. However,
app-defaults files can #include other files, so you can make the
locale-specific version include the generic version rather than
duplicating common settings.
