This isn't going to be popular but I'm going to have my say on this.
This is akin to the Catholic church saying "the bible seems a bit out of date, lets rewrite it".
There are a number of reasons why they don't. Any ambiguities are already there. They aren't creating new ones. And "This is the Word of God".
ENaG is the same. It is written by an FES prophet. Someone dead and unable to be held to account. Someone revered and delivering first hand their thoughts on their findings. Not someone 150 years later reinterpreting the text for their own good.
By placing your thoughts of what the text may be saying into an annotated or updated version, you narrow that level of ambiguity and give your enemies specific things to target. Its then harder for you to say, well maybe I misread Rowbotham. I fear all that will come of this, is a narrowed selection of topics around ENaG, focussing on your misinterpretations, not the theory as a whole.
ENaG is a holy book for the flat earth society. There is nothing else like it. We are its guardians, not its editors.
If you have the energy to write a whole new book, write a whole new book ... but distance yourself from replacing the text that founds the society.
