Folder per language?

We are interested in splitting up the files for any given language based on purpose. For example:

```
  i18n/en
    countries.json
    errors.json
    general.json
  i18n/fr
    countries.json
    errors.json
    general.json
```

Is this achievable with the current code base? If not, would this be a functionality that could be of interest if coded?
