Question regarding OEM crankshaft "reverse engineering" into billet crank

So, let's say you have a diesel V8 that has a few from production that are known to snap cranks in a particular spot, and there is no solid answer as to why it happens. Your goal is to have a "mocked" billet variant with the exact same measurement specifications to reduce the chance of it snapping without changing anything else if possible.

Firstly, is that possible without changing other internals? Also, is a different harmonic balancer required? Are there other factors to making a billet crank that would mock an OEM forged crank and swapping it into the block?

For anyone wondering: 5.0 Cummins
