Many changes of that kind have been made by the faster-cpython team I believe, Mark Shannon was rather focused on it (and had a decade of experience of that kind of tweaks to python).
But I'm trying to find/recall a blog post that detailed the different steps in shrinking the CPython object struct...
If you say that's not enough, more radical changes needed, I would understand.
Given any arbitrarily optimized thing, it is always possible to optimize it more. And the fact that it's possible to optimize it more is not meant as a criticism of folks who did the previous optimizations.
So, I have no doubt that Mark and others have worked on exactly the thing I'm talking about and that they've gotten wins. And I have no doubt that more can be done. Also, not saying I would do a better job at it than Mark or anyone else

Gotta be careful about the tone and mindset here.
