This sounds doable in the Style's SQL Statements. Currently we use

SELECT name AS local_name,
        COALESCE(tags->'name:en', name) AS display_name
   FROM planet_point
  WHERE tags @> '"place"=>"country"'
    AND NOT name IS NULL;

but we may also use
SELECT name AS local_name,
        CASE WHEN name != (tags->'name:en')
             THEN name || ' (' || (tags->'name:en') ||')'
             ELSE name
         END AS display_name
   FROM planet_point
  WHERE tags @> '"place"=>"country"'
    AND NOT name IS NULL
  LIMIT 10;

I could set up such a style on the toolserver if it would be helpful, 
but I'd like to point to the localized maps we currently have in >30 
languages: http://toolserver.org/~osm/locale/ (use the layer switcher).
