Quantified as what? When you are optimizing things, it's useful to have a numeric value that you're trying to maximize (or minimize).
Sure, but I doubt that the optimal ramp for brown adipose tissue activation is that much different from the optimal ramp for mood / energy adjustment, or the optimal ramp for immune strength, or so on, and by optimizing for one of those things rather than none of those things you give yourself enough of a feedback loop to prevent ramps that are harmful overall.
I would find it difficult to optimize in the short-term for mood due to noise and confounders, and pretty much impossible to optimize for immune strength since I have no easy way to measure it.
In my experience ramps are not needed at all, so I would expect that even for people who would like one it would take time on the order of a couple of weeks which is way too short to optimize for something that you can't easily measure directly.
To the fun theory, hedonic treadmill sequences.

From the article:
"In hedonic reversal, a stimulus that initially causes a pleasant or unpleasant response does not just dissipate or fade away, as Irvine describes, but rather the initial feeling leads to an opposite secondary emotion or sensation. Remarkably, the secondary reaction is often deeper or longer lasting than the initial reaction. And what is more, when the stimulus is repeated many times, the initial response becomes weaker and the secondary response becomes stronger and lasts longer."
