The anonymity weakness is that operating system updates are well-known.
If I know that state of your machine or can influence it (eg. by
blocking certain updates for you), and have sufficient information to do
a traffic correlation, ...

It reduces your anonymity set, at least from a research point of view. I
don't say I oppose your ideas in general, I just wanted you to be aware
of that. But maybe I'm completely wrong here, some of the Tor experts
certainly know better than I do :)
