I googled a random engine hoping it had similar ratios, but that looks like a failed plan. I'm on board with what you're saying, but not as drastic. I'm seeing a 10% increase with head-milling, and a 3.5% increase with bore increasing.
No matter the numbers, looks like milling can get you pretty substantial gains in compression. Like I needed more reasons NOT to get a turbocharger for the 230...
