Voynichese is a numeric cipher?

[ololololo]

A good intermediate result would be just showing how the system reproduces the statistics of Voynichese.

Just to be clear. When people say "a system that reproduces Voynichese statistics," they usually mean an algorithm that tries to follow ALL the characteristics of Voynichese (repeats, word similarities, low entropy, etc.), because they are understood as something composite. 
From the point of view of my theory, all these features are mostly the consequences of secondary encryption. In any case, I'll have to change the text, which in its pure form will not be so convincing in appearance.
Of course, I can try (and plan to do so), but it seems to be useless.
