Reese, I've been in manufacturing for 40 years & from my experience, when doing a deep draw, most tools will make a bigger bump in the sheet first, to get the metal stretched out, then the forming tool will squish it back to the shape you want. Trying to get all that metal stretched into that tight pointed end all in one draw might be a challenge. Don't be afraid to push a little, then anneal, then repeat (several times maybe). There's a film out there of all the steps it took to form the oil pan for a model T ford....back in those days they didn't have progressive tooling. They annealed the pan several times as it slowly took shape.
Bottom line is this could be more labor intensive than you think. Good luck.
