I believe 469 uses something around the same thickness, in various diameters, for basically everything, with rivets holding everything together. Very very lightweight.
We've used material as thin as .050 and .063 in drivetrains, back in the days before mandatory bumpers (we had no bumpers, they lived).
As to tubular frames, how about this: http://www.chiefdelphi.com/media/photos/12949 and http://www.chiefdelphi.com/media/photos/12952 (same robot) - Chief Delphi 2000

It just takes a patient welder

This is a weld I did in college, but one of my students two years ago was welding soda cans together like this for fun in her shop class. It is certainly non-trivial, but definitely doable.
