The point of stressed skin is not that you walk around on it with yer boots on - it's that for wind and snow loads, the stresses are evenly distributed.
If you want to do a frame, and get the full benefit of the hexayurt geometry, why not do it this way? http://www.appropedia.org/Hexayurt_frame Keeps the ultra-low waste property, and can be adapted to have panel materials by tweaking the geometry slightly (this one is optimized for fabrics.) Make the 12 "dominant" triangles 8' x 8' isosceles, tweak the ones which are equilateral in this version to whatever gives an appropriate geometry.
