It seems to me, that this CGI project is so accurate, there shouldn't be any reason why a builder wouldn't be able to build a replica.
They've done them with several Axis (there's even a replica KI-43 Hayabusa!) and Allied machines, so why not the A6M8? Perhaps this project (and thread) might bring about that very thing...we can only hope!!
Looking forward to your next progress report, Shinpachi!
