I have an idea that comes from the Remixed edition of Ubuntu that a
guy here from Sweden released on his FTP.
Take a look here:
Note: The page is in Swedish.

Perhaps make several ISO's for the parts of the world.
For instance:
Mageia DVD i586 or x86_64 for Europe containing:
Denmark
Finland
Germany
Norway
Sweden
And all the other countries TO of course.
In the installer you choose to install Swedish & you'll get only
locales-se or -sv instead of both locales-en & locales-se or -sv
That saves a lot of space to preserve for other needed packs that
won't fit in the original-iso.
