I hadn't heard of anything but I've always thought that idea sounded pretty cool myself, so I looked it up. Looks like someone did write a book about him! Decent reviews, too, and it's free on kindle. I haven't read this, but I might, since as you say the idea is quite intriguing. https://www.amazon.com/Trials-Obed-Marsh-Matthew-Davenport-ebook/dp/B07BCYJ6W5
