They don't really need to iterate more on Soyuz. It's cheap to build and reliable so long as Ivan doesn't get drunk and let an American astronaut woman start drilling holes in it. The only changes you might want to make are ones that would make it even cheaper to build and operate, but those have to be pretty rare at this point.

DOS modules could see some updating, but they're pretty much just a pressurized can with equipment packed into them. There's very few dramatic changes you can make to a simplified design like that. The best you could do is replace older components with newer, lighter, cheaper ones.
