They have been showing off single units made from shipping containers for a couple of years now at the Kentucky State Fair. Went through the two they had last year, very nice inside with ALL the amenities included. The outside does not look like a container either because of the windows and doors. One photo of a model also showed it to have a small deck in front. They look like some of the "Tiny Houses" you see in the TV series of that name. 
So my opinion is why not?  Most definitely would be having to live in a tent or just a sleeping bag under a tree or bridge somewhere.
