Yes, it is possible. Unfortunatly, if you have a cast iron riser, you will have to chip out the concrete to get low enough to cut the riser to install a Clamp-all and a piece of PVC pipe. This might not be possible if you have a short riser. Then you would have to cut the cast iron behind the 90 degree turn. Either way, it's a pain in the butt. Call a plumber. It will be worth it.

Can you cut into cast iron soil pipe with plastic soil pipe?
You can put up to a 2 inch pipe into a 4 inch. If you are putting 4 inch to 4 inch, either take out a section of the cast and put the PVC in or cut out a section and connect the PVC to the cast with rubber sleeves meant for this. You can use a saddle clamp for the 2 inch. It is a half round piece of PVC with a 2 inch connection in it. It is held on with two U bolts that go around the cast pipe. Put it where you need it and mark the 2 inch hole on the cast. Drill a series of 1/8 inch holes around this circle. when you get them all drilled, you can break out the plug. Try to keep it from falling into the cast pipe. Put the saddle clamp on and connect the PVC pipe as needed. Seal the saddle clamp to the cast pipe with plumbers putty.
Changing iron waste pipe to PVC?
You just do it. Big help I know. There really isn't a question in your question. You cut the old pipe out and replace it. There is a chain cutter available that has a series of cutting wheels in a chain that you tighten down against the pipe and it basically breaks the cast iron pipe cleanly. Use a rubber coupler to connect the cast iron stub with the PVC. This is a short piece of rubber tube the right size to fit the pipe you are working with and is held on with 2 hose clamps. Where the cast goes into the floor or wall, you can take out the last section of cast and insert the PVC into the flare on the piece in the wall or floor and seal it as you would a piece of cast. Without a specific question, that's about all I can help you with.
