Lao Fonts and Google Docs Lao Script Support

There are two SIL OFL fonts that would be great to have on Google Fonts, if possible:

**Saysettha by Dr John Durdin/LaoScript**
[Saysettha TrueType Font Collection](https://laoscript.net/download/saysettha.ttc)

**Phetsarath OT, a Lao government font:**
[Phetsarath OT](https://www.phetsarath.gov.la/File_Download/downloading.php?id=cfcd208495d565ef66e7dff9f98764da&rec=0)

Would it be possible to add these? If not, what keeps them from being good candidates?

It would be great to have some Lao support inside of Google Docs - and to my udnerstanding having some Lao fonts is a good first step towards that, correct?
