Sadly, I suspect that any attempt to provide in-camera baseline calibration adjustability would ultimately result in so many support calls and increased support costs that no manufacturer in their right mind will consider it. What I'd like to see is not a "deep in the menu system" way to do this but a professional quality companion application (NOT like that wretched Pentax Photo Browser/Lab suite ...) that would allow instrumented calibration and tailoring of a camera or set of cameras' metering and white balance baseline values. Make it expensive enough that the majority of 'common folks' wouldn't muck up their perfectly fine cameras, but allow those who actually would get some advantage from being able to calibrate all their equipment precisely a means to do it. It's the sort of thing that a service tech should have at their disposal. Same application could also set new baselines for the JPEG rendering algorithms, and a service tech could use it to make customized 'improvements' for those JPEG 'common folks' who find excellent quality default JPEGs inadequate and want cartoonish, overly crunchily sharpened results direct out of the camera on green mode.
