I don't think there is a limit on the bagged content regarding weight or biology that is imposed by FIRST. The bags are big, but putting a machine shop inside would be a literal stretch. Then there's the support of your contained crew. NASA may have some hints about that. They would certainly be interested in a device that enables long-term bag habitation, even if it was not part of an actual FIRST robot. Feeding and breathing through small tubes that could pass through the bag's "neck" gather under the seal ziptie would also be a large turn off. Dr. Flush (of Hamilton Sunstrand) would also have some commentary about the most frequent question concerning space station life.
Cute idea for a picture though. I'm already trying to think of a caption for it in case it makes it to a contest.
