There's a lot more to it than just measuring force. For an extreme example, imagine delivering the same punch (force, target, etc.) to Mike Tyson in his prime versus a 90 year old lady.
People who know how to absorbed and redirect a blow minimize how much their brain gets tossed about, but measuring peak acceleration of the skill is going to show how much someone’s brain got rattled. It’s a solid structure and your brain is inside
Also a you don’t see 90 year old grandmother’s in the ring. So it’s true someone with a larger head has an advantage here, but mechanical properties of tissues should be fairly similar between fighters and acceleration accounts for the mass of the head.
