It's always good to see people thinking creatively!
I know your thesis is theoretical, but there are some real-world considerations that might to useful for you (and others who may be curious about how A.T. shelters are built) to be aware of:
First, there is the overarching issue of what the A.T. experience is all about. The Appalachian Trail Conservancy, in partnership with land managers and trail volunteers, has developed the following definition of the A.T. experience:
The sum of opportunities that are available for those walking on the Appalachian Trail to interact with the wild, scenic, pastoral, cultural, and natural elements of the environment of the Appalachian Trail, unfettered and unimpeded by competing sights or sounds, and in as direct and intimate a manner as possible. Integral to this Trail Experience are:
opportunities for observation, contemplation, enjoyment, and exploration of the natural world
a sense of remoteness and detachment from civilization
opportunities to experience solitude, freedom, personal accomplishment, self-reliance, and self discovery
a sense of being on the height of the land
a feeling of being part of the natural environment
opportunities for travel on foot, including opportunities for long-distance hiking.
Another issue to be aware of is that of permissions from land-managing agencies. Depending on what part of the A.T. you are considering, it might be the National Park Service, the U.S. Forest Service, a state park or forest, etc. You'd also need the approval of the local A.T.-maintaining club and ATC. There are formal guidelines for Locating and Designing A.T. Shelters and Formal Campsites.
The A.T. might not be the best place for your shelter concept, but your shelter might be just the ticket for other less primitive trails or settings where the technology and design would be welcome.
