Can CGPT, or any AI model out there, that will allow me to convert a book’s style? Meaning I want to have it convert the book to a unique writing style and provide examples relevant to my job?

So just to summarize
- Let's say I have a book called "How To Think Through Math Questions".
- The majority of the book is how to think through problems, and the examples it gives are math problems because that's what the author is familiar with
- Let's say the author is from Japan, although the book is in English, it's a been broken because it's the author's second language

So given the ability, other than copy/pasting sections in GPT4 and saving it into a new document, is there a way I could just have a single program "convert" the book so it does something like
- It keeps the same general style of explaining how to think through problems
- It replaces all the math problems with computer/tech related problems and scenarios
- The author's writing style is something like, say, CS Lewis

Anything that can do this easily you'd say?
