Not sure if you're still following Luwx/Lightly, but there's a fork of it - boehs/Lightly (though for what I've seen the changes it has had have been imperceptible).
These are some good tweaks! Personally, especially the smaller changes like uniform sizes for controls, would be worth taking up with the KDE community because they might consider merging them into breeze proper. Unless it doesn’t work like that for theming of course!
