Personally I'd be very interested as long as the interior space remained the same. Something like this.

Seen these before. Not a big fan of the top one (though if I remember correctly someone actually built it). Just too off the wall for me. The grey one, kind of neutral about. Don't see these as truly viable from a mass production stand point - these are someone's personal design "dream" or what have you. For it to make mass production it has to be a final design that would appeal for volume sales. I don't think either would do that. But that's just my opinion.
