A fun thought, but I think there's a huge difference between someone random (like me) vs. someone who has spent a lot of time and effort developing the craft of writing. And I'm certainly not unique; thousands have hiked the AT and PCT, and we're into the hundreds now that have done the CDT, including some that have written books about it.

Maybe if I get really bored and think of a unique angle (there are so many "I hiked this big trail" books out there already).

It's interesting to hear that it's easy to put up Kindle content like that. A nice idea for anyone that has always had a book in them trying to claw its way out!
