Probably cost $ millions to pull that off, if at all.
200-ton blanking press.
600-ton transfer press.
Multiple tooling.
Multiple passes to achieve depth of draw without tearing.
Perhaps some heat treating ( annealing ) between strikes.
Today's high strength steel, B-Pillars, must be formed when red-hot.
