PicoTTS support for HASSIO ? (Cloud-less Text-To-Speech)

Since PicoTTS support was in Hassbian, and many of us wish for cloud-less TTS but cannot for the life of them find out how to install PicoTTS on a HassOS/HASSIO system:

Could we please have a HASSIO addon that brings PicoTTS support (probably also installing the PicoTTS engine into “HassOS”)?

Cheers for the votes. Keep ’em coming …
