I like your idea, but foresee lots of cracks and popped bubbles in your clay. Due to uneven heating and the sheer sizes you're trying to fire. I was just thinking about building a sandbag house, and thought about doing something like a exterior coating of ceramic fired with a tiger torch. However the more I think the more I realized, naw probably be better to drop a layer of poly and cover the whole in soil make a mound home plant some grass and flowers and keep some bees.
