Roy, I don't know how I can convince you that what you're doing is original research. I can only ask you to look up any of the books in the bibliography, in either section of it (the first section is books used in the article, the second section is books not used), and do a search for "four kingdoms" or "dream of four kingdoms", and then try doing "five kingdoms". I doubt you'll get any hits at all for the second search, and you'll certainly find that four is the commonly accepted reading. But DIY Hebrew is definitely not allowed.
