Greek Voices

I am developing a spoken Koine Greek language-learning application and have been experimenting with Kokoro-82M. Although Kokoro currently has no Greek voice, I discovered that af_bella can already produce surprisingly good Greek speech when pronunciation is supplied explicitly through Kokoro's phoneme override syntax. For example, reconstructed Koine: [Ἐν ἀρχῇ ἦν ὁ λόγος](/en arˈkʰe en o ˈloɣos/) produces quite convincing speech with Bella. A native Greek-trained Kokoro voice would be extremely valuable, particularly because Greek phonology and prosody would provide a much better base while allowing applications to supply historical Greek phonemes explicitly. Is Greek language/voice support planned? If not, what would be required to contribute or sponsor development of a Greek voice?
