Alternate font version?

Toki pona has an alternate writing system called sitelen pona (it has many, but it's the main and most official one). If I (or someone else) wanted to add an alternate version of the toki pona translation (probably with some minor text changes and a lot of reformatting), what would be the options? (The current version in a Latin script would continue to exist.)

• A couple of computer fonts exist, and of course one with a compatible licence would need to be picked. linja suwi has a GNU AFFERO GENERAL PUBLIC LICENSE, would that work?
• If this was added to the website, that would require a new language code, right? There is no other option?
• Is this even something you want to add to the official project?
• If no, would it make sense to store them in the repository anyway, without displaying them on the page? (Is that even possible?)

I considered doing this locally anyway (after finishing translating all episodes), but until someone asked me if this could be open for contributions, I didn't consider adding it to the main project. So I thought I'd ask.
