Those are definitely drool-worthy. The closest I have to that, weight-wise, is the old 2nd-generation Kooka cranks, in anodized black. They have that allen-bolt-type of deal, holding the crank-arm to the spider, but I'm not sure if that means swaged or not, after reading this thread. (?) For an excellent square taper BB, try to find the old Race Face titanium-spindle BB, that was sold around the same time as their original Turbines. The cups are an anodized light blue, very much like the chainring bolts just recently posted, color-wise. I wish I could find another one, with Italian threads.
