I would too, I hope he decides to release it. Even if the Greek font is a little on the non-standard side (at least compared to most scholarly works I'm familiar with). Early Church history is definitely something I'm becoming more interested in. Right now I'm starting to work slowly through the NT in Greek (slow going), and have just started to teach myself Coptic. Good times!
The Old Church Slavonic is also a little strange, but since I can still read it that shouldn't be a problem. It's great that you are learning Coptic! I would love to learn Hebrew and Aramaic to study things like the Dead Sea Scrolls, as well as Greek to compare the differences between the NT translations and map it all a little closer to the source... but that might be just a dream at this point. The field is not exactly the most viable career path at the moment, or that's what I hear.
Greek isn't actually as hard as it's made out to be. If you decide to do it, I can help!
