That's a pretty interesting way to try to make brass competitive with true velocity etc

Good luck getting a decent and easy to make and measure datum for the headspace.

Also on my FEA simulations of cartridge cases a conical shoulder was never the issue, however the joints between it and the neck and body are, but it can be easilly solved via generous radius and cadequate clearance between the case and chamber. The "flat# bit doesn't need to be big, just enough to have a reliable reference point.
