In seriousness - of course putting this in your house is a a pretty risky and likely dumb idea.

Would it be possible to design a minimal, modular metal rack to act as thermal isolation? I could picture a scheme with metal bent into a shallow Z shape with obtuse angles, which would direct the burning debris from a failed battery away from all the others.
