My Solution – Abbreviated Middle High German

[Stefan Wirtz_2]

[..] 
Regardless of whether my translations are correct, do you think it is possible that the author could have written the manuscript in this way?

Unabhängig davon, ob meine Übersetzungen korrekt sind – haltet ihr es grundsätzlich für möglich, dass der Verfasser das Manuskript auf diese Weise geschrieben haben könnte?[..]
 

There is a bit of a contradiction:
Maybe there was an author with such idea; but the VMS was written by probably a small group of scribes.
To write all this as fluently as the texts do look, all involved persons would have had the need of understanding the "shorthand / abbreviation system" of the 'author', since even just copying such a non-natural writing would have been a hell.

So, honest answer is 'No, the VMS could not have been written in this way',
but also 'Yes, everything is possible, some author could have had the idea to produce a notebook with simplified entries'.

But as several people seem to be involved, that last idea is quite unlikely.

Openly, no one here appears to be willing to answer your question with a simple 'yes' or 'no':
'No' would mean you wasted your ~2 years just useless and is quite disencouraging,
'Yes' would upkeep your (uncertain) dream of having a solution and let you just wade deeper into the tar pit.

Personally, I don't see any of German/Germanic language structures within the Voynichese; 
that is a false trace to follow, and seeing you doing 2-letter-'deciphering' into long words, is not convincing at all.
