How to manage translations when a site is being re-installed frequently? Sites built on a profile, will, during it's early development experience frequent re-installs.

If a translator makes changes to a site, these will get lost when the database is dropped.

What options are there for handling this, in a way that survives re-installs?
The only way is to make a copy of the translation options.

I'm not sure if a hook_cron or a drush can donwload the files, if not the only way is to donwload and them copy into 
../profiles/myprofile/translations/*.po
