Except you need the shuttles robot arm to man handle the new module... and they don't fly anymore
First, both Zvezda and ICM have propulsion. That was the entire purpose of those modules. So I *think* that such a mission could at least ostensibly involve the old Russian module giving the rest of the Russian segment a small push with its thrusters, followed by a push back the other way to stop the motion away from ISS, followed by undocking, followed by Zvezda doing a deorbit burn to pull it downwards and away from ISS, followed by ICM doing the same basic set of maneuvers in reverse.
Second, even if that is determined to be too stressful on the interconnections between modules, the ISS has Canadarm2 permanently attached, which is what was used for most of ISS construction. As far as I know, the shuttle's arm (Canadarm) just moved each piece or module out of the Shuttle's bay and handed it off to the ISS arm, which put them in place. Note that Zvezda wasn't brought up by the shuttle, and nothing would necessarily require a self-propelled module like ICM to be launched in a shuttle, either. Even when fully fueled, it is well within the weight capacity for a Falcon 9 in its reusable configuration. It's slightly lighter than an fueled crew Dragon capsule. They would probably need to give it some sort of protective shell or something, but it seems like it should be a pretty straightforward lift.
It's probably worth noting that apparently ICM was never fully completed, and it could take as much as 2.5 years to finish it, but it is still in storage at last check. And apparently others have proposed a similar solution for keeping ISS operational without Zvezda, so this isn't an entirely crazy idea.
