Hi Lunch box, welcome to the forum. I am impessed with your ideas about your camping project. Building small is right down my alley. Heck, I have actually been known to build teardrops that are only 6 feet long, another 4 feet long and the smallest, 3 ft wide and 3 ft long. They all sleep one just fine, and if you don't mind, all I can suggest to you, is that you forget about that tent, build a real teardrop trailer that you can just back up into a campsite, kick off your shoes and go to sleep.
I am a bit surprised that you enjoy unrolling a canvas tent, propping it up on poles on rocky and uneven dirt, then try to drive stakes in the ground, tightening ropes and zipping up flaps to keep the rain and bugs out, blowing up mattresses, setting up canvas cots, then contending with wild animals invading your sleeping area, all the while enduring the uneven, and often soaked ground due to possible flooding in the middle of the night, by a sudden downpour.
These are some of the things that I remember, prior to building and enjoying a waterproof teardrop trailer. Now don't let me sway your interests in tenting, after all, that is how it all started and many of us have done it at one time or another. However, now as a teardropper, I always enjoy a quiet, comfortable, warm, well lighted, dry hard-sided, bug proof, sleeping enclosure, quite unlike the torture I was subjected to while camping with my folks when I was just a kid. I say, build what suits you, take pics as you go along, and perhaps we will cross paths out there in a quiet campground somewhere. Good luck on your build. Be sure to post some pics of the end result, I am sure it will be interesting, and surely different. No one's build is "wrong", I know, I'm a bit of an iconoclast as well. I design 'em, build 'em, then show up at a campsite and sit back and enjoy the on-lookers reactions. I think it is geat, go for it. Camping is good for rejuvenation of the soul, I know, I do it as often as I can. After all where else can you go to find interesting friends that you haven't met yet? Again, welcome aboard, ask questions, post progress pics and enjoy..........
