Oh yeah. Replace the stainless steel by carbon fibre, give it to your pals of Boing and instead of being ready in 2030 for 2.3 billion it will be ready in 2050 for 50 billion.

Much better for making your friends rich.

Carbon fibre second stages that melt/burn up on re-entry.

And? We still have yet to see whether full re-usability of the second stage is the best approach. The Neutron approach is really interesting, they can make the second stage incredibly light and cheap. Blue Origin claims the economics of a super-cheap disposable second stage, even for as one as large as theirs, is pretty much equal to a more expensive and heavier reusable second stage. (they're developing both in parallel to see where the chips land).
