I don't think it has even been a problem to find a way to convert plaintext snippets into Voynichese snippets without any difficulties. And if nulls are involved it has never been a problem to explain the how of 'chol chol chor' (not the why though - why make the nulls obvious this way). The problem as I understand it is to match the large scale statistics of the manuscript.
Also, if your method involves sorting letters in each word, I think it's not encryption, because the underlying text is mostly destroyed. There is no way to tell 'read' from 'dear' or 'news' from 'Swen', it's just a way of generating garbage from a plaintext.
