That's basically what I'm thinking of in a hexagon,same as the tent was... but adding a floor with bugscreen on the perimeter for a couple reasons;of course to keep the bugs out;but also for an easier pitch(stake/stretch out the floor and just raise the center pole in place) and you can raise the tipi off the ground for better ventilation with the bug mesh holding it secure.I've had problems with setting up tipi type tents without an integrated floor..set it up and then you just gotta keep adjusting the sides of the thing,moving stakes to get the layout right.. until things get tight because there's nothing to signify where the stakes should be to make everything
just right.If you have a floor connected to the tent..stretch out the floor that would be attached to elastic bands at the points to correspond to the seams on the tent.Crawl inside,place/stretch out the centerpole until everything is tight(or hoist a tie-off rope from over an above branch and tie it off) and you're done..no more adjustment needed.
Without a floor,the stakes need to be eyeballed or the tent setup and held upright by just the centerpole(and someone holding it),then go around it a few times to get things right..too much fiddle-faddle.
In better weather with the integrated floor,the tent sides can be stretched upward to allow a perimeter of air with the edges 4" off the ground and the mesh exposed keeping the bugs out.If the weather cools,drop the tent about 4" and batten down the stakes,takes about 1-2 minutes..
I could add a "Stretcher" hexagon of small 12-16" poles that would correspond to some tie-offs near the ceiling that would stretch out the single peak point to more like an umbrella inside,adding more headroom in the middle and adding the minimal weight of 6-small aluminum poles held up in space inside the tent(or outside)..and couplings at the corners.
It's too bad that website has so many pop-up windows..makes one want to leave FAST!
Also..I would think sewing one from a dome tent fly would be pretty simple.The exterior bottom corner stakeouts are usually already on the fly,and so is the zipper in place.It's just a matter of slicing the seam areas,and resewing those six new seams,reinforcing the middle top point for a pole point,maybe adding a couple vents of mesh near the top on two sides(or only one)with a cover from the material removed.Once that is pitched right and tight for testing,it's easy to measure for a floor,make it up to specs, and sew it just inside or to the bottom edge to keep water outside the mesh.Rain should just roll down the mesh even and stay outside the floor area which would probably be a little "bathtubbed" by the tight mesh.
