I went into a pretty deep dive into dozenal systems a few years ago. I really like the dozenal unit systems that people have came up with and even designed my own. I don't exactly remember what I had but I think I tried keeping all of the metric base units and then multiples of 12 from there.

Some of the dozenal measurement systems try to replace the second or meter, for example, which I don't think would be necessary. And some also try to redefine the clock, but honestly 2 sections of 10d hours is more than dozenal enough. And I like the blended base-60/base-12.

What's really interesting is trying to extend the calendar to base-12. Depending on whether you want to keep the 7-day week or switch to 6-day week or abolish the week altogether[1], you can come up with several different interesting concepts.

[1] Even though it had 7-day weeks, intercalary days outside of the week is what shot down the closest we've got to calendar reform since Gregory. https://en.wikipedia.org/wiki/World_Calendar
