Could the Greek font be made Classics-friendly?

[anothergitinthehub]

Absolutely love the font! Has the perfect feel what I'm doing: annotating drawings for learning classical Greek. However, the font seems to be missing the extra diacritical marks on letters that the ancient language has, but which are lacking in the modern one. Is it too big an ask to add the versions of the letters that have those extra squiggles? And may we get the half-stop too (the single dot that was their version of the colon)?

Thanks again for your work on this font!
