Voynichese is a numeric cipher?

[ololololo]

Here are a couple more sentences from Lorem ipsum that I decided to encrypt.
Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu. In enim justo, rhoncus ut, imperdiet a, venenatis vitae, justo. Nullam dictum felis eu pede mollis pretium. Integer tincidunt. Cras dapibus. Vivamus elementum semper nisi.

Inside an anagram, we have the right to rearrange the letters. We can also add numbers inside the anagram to get a different letter from the alphabet. In the case of Roman numerals, this won't result in any loss of information or make the decryption more difficult (for example, to get VI, you can simply add V and I. I believe this can be quickly achieved visually).
1). o oke a ok iin - a moves between ok and iin: okeo okaiin
2). chor oin daiin dy -  The problematic oin can be replaced with... The gallows p/cph: chor cphdaiin dy (or chor cphdy daiin)

3). eor dan ol d a - The last a turns into ey. Add a garbage ch: cheor chedan chol chd chey (maybe cha)
4). chol sheol oiin dan or or aiin - A little trick: we split or or into oro, and r goes into the next word: chol sheol oiin dan oro raiin
5). ote aiin - oteaiin
6). chor sheor oin on ote dan dan a a a a - a series of the last a's is disturbing, but we can add them up to get XX (sh): chor sheor cphy qo otey dan dan sh (maybe dan shdan).
7). chor a - chor ey - chor chey
8). chor sh oiin on daiin or a - chor shoiin qodaiin or am
9). chor eor oin ol - chor cheor cphol
10). eol daiin y - cheol daiin chy
The nulls are highlighted in bold. As you can see, the text can be "edited" without using any rules. 

Again, I would like to point out that this is a clear example, not an attempt to accurately reproduce the text of the manuscript.
