Yes, possible, or at least one choice :)

For the first thing, hack on the Harmony String is CLEAN, Apache Harmony has
fully implemented the JRE, jvm plus classlib :)
However, hack on the String is one of the choices. On the other hand, for an
example, we may have a line of:
throw new RuntimeException("Love");
and after our injection, this line will become something like
throw new RuntimeException(Messagers.get("Love",thisLocal));
where "Messagers.get("Love",thisLocal)" will return some translated words
for the local, e.g, "Amour" in the language of Franch, or "Liebe" in German
;)
Further more, we may ignore some hard-to-analysis words/sentences but only
focus on the ones which are easy to apply the localization? :)
All kinds of ideas on design is welcome at this period. Please tell me if
you have more questions :)
