[Question] Overvolting a PSP 1000 CPU by hacking the Pommel IC (DC-DC Converter)? Schematics included

Hello, I know a bit about Software and Hardware but would like to get your input on a highly specific hardware mod I'm researching.

I’m looking to physically overvolt the CPU of a PSP 1000. My idea is to hack the "Pommel" (Sony's custom power management IC / DC-DC converter) or modify the surrounding hardware. Rather than swapping out standard voltage divider resistors, it looks like this circuit relies on feedback filters. My goal is to manipulate these filters to trick the regulator into delivering a higher core voltage to the processor.

I have the official schematics and PCB layout for reference here:https://smallpdf.com/share-document#r=result&t=10743861ab24e78cf571f03022870b5a&i=share

Since this is deep into uncharted territory for this console, I’d love to get some general advice from people experienced with altering DC-DC feedback loops on densely packed boards:

• Target Voltage: Looking through the schematics, I am targeting the CORE_+1.2V rail. Do you agree that this is the right and only voltage line I need to raise to successfully overvolt the processor? Or are there secondary rails that need to scale alongside it for stability?
• Analyzing the feedback loop: How would you approach pinpointing the specific feedback filter components tied to the CORE_+1.2V generation?
• IC Protections: Does anyone have experience with Sony’s custom power management chips from this era? I'm wondering how aggressive the internal overvoltage protection (OVP) might be if it detects an anomaly on that 1.2V rail.
• General Approach: Any advice or warnings on methodology before I start testing or altering the traces around the Pommel?

(Note: I'm fully aware of the standard CFW 333MHz software overclock; this project is strictly about exploring a physical hardware voltage mod).

Thanks for any insights or help analyzing the schematic!
Maybe a collaboration would be possible where I buy another PSP 1000 and test the hardware mod and someone helps me identifying how to do it.
