35 years back I encountered pretty much the same problem in our first house. A 25' long cast iron main under the concrete basement floor, that was about grown shut and was rotted pretty bad. I didn't have extra money so I used a big chisel and maul to knock out the cement above the pipe and replaced it with pvc by being careful to not disturb the original bed. Its still working fine and my cost was about 3 days of hard work and whatever the pipe and bags cement to patch it back up cost back then which wasn't much. Nothing too difficult about the process, just tedious manual labor. They have rubber fernco boots that will connect pvc to the cast iron if you have just a bad section.

Jack hammering up the entire house and opening up several walls is a ton more work than digging a trench in dirt and sawing a section out of my driveway for the kitchen reroute.
If your pipe is that bad, you are just kicking the can down the road, so to speak. I say, do it once, do it right and never touch this again.
