I think your first two points are mostly trivial to address - put a board going beneath all the steps and add a handrail. The bed seems a poor idea to me too though. Maybe if it were just for one person or if you used a futon that you'd roll up. Isn't a futon more in-line with the micro home concept anyhow?
