Yes, the math works.

No, there's not a chance in hades it would work in the real world. FWIW, over the past fifty years, I've seen three professional attempts to do what you describe, a flathead Ford V8, a SBC and a Studebaker V8. None of the three could be sealed to hold coolant. Just too many inches of weld in cast iron.

Blocks which are designed to have pressed wet sleeves are made completely differently, with what might be termed an exo-skeleton. A solid cylinder block, such as the Packard, with the cylinders machined out doesn't have the internal reinforcement under the block deck and resultantly has the rigidity of a cardboard box.
