I get where you're going with this, but due to the way pricing and royalties work on Amazon I feel that it would be very difficult to make a profit this way.
Plus, honestly, the market is already saturated...isn't it better to leave Amazon and KU to indie authors working hard to put out novels? More content just makes it harder to get seen, and it's not a platform mean for this kind of short-form piece.
I'm curious to see how your experiment goes but I'm also concerned about how this mindset might impact the market long term.
