Lateral Sewer line question- tie-in and/or insert

I have a cracked cast iron 3 inch lateral main line that I have dug up in my basement. I have reached the point where it connects to 6 inch clay under the house foundation. I have two questions:

1) From a video, I know that the clay pipe has roots at the joints and I am wondering if while I am replacing the inside pipe, if I can insert (ie, shove from the basement toward the street) 4 inch PVC from the basement to the city line. This is about 30 feet. The obvious advantage is that I would not have to eventually dig up the yard.

2) I assume that there will be several comments on why option #1 is not recommended. So, what is the method for connecting the 4 inch PVC to the existing 6 inch clay? It appears that the current cast iron is sealed with cement of some kind, although, tree roots have broken through this.

Thanks for your help.

Your right not recommended, replacement of a sewer line needs to be permited, means you have to dig out the entire line, make proper connections, and get it inspected.

Sorry I won't tell you it's ok to do it that way.
