Although we've been using dome tents for years without problem some of the areas where we camp have had increased bear encounters including several maulings and a recent death and I've been looking in at this forum over the winter with an idea of building something similar in the future for increased bear safety, at least at night.
This isn't exactly what I'm interested in building but here's a concept model that I saw on the net which is probably more for fabric molders but shows some good aerodynamics and volume reduction, about halfway down the page;
