It's hard enough to do some of these things, without making it impossible.I think it could be done, given the right tooling. The process wouldn't be properly called "drawing" - it'd be more akin to swaging over a mandrel. Of course, it would be uneconomical...
But back to John's W-W with the stepped inners. Seems you'd either have a really thin wall up towards the cork barrels of a rather thick wall down at the stockings.
