I’ll check it out, but two problems I notice right away is that this assumes Genesis was written by Moses at the time of the Exodus, which is by no means a given. And also it would be very difficult to fudge the geography of Genesis 2 so that Israel is Eden. The author would have to be extremely ignorant to believe that the Tigris and Euphrates join together in Israel, let alone the other two. To me it seems that the intent of the text is that Eden no longer exists. It was a geographical place that existed at the time of Adam, but no longer exists for one reason or another.
