Are rubber donuts that fit into the XH cast iron hub and transition to 3" PVC allowed in Pennsylvania?

I am trying to have a fallback position if my attempt to replace a corroded cast iron toilet flange and a corroded section of waste pipe causes damage to the closet elbow, and I then have to remove a much larger section of cast-iron pipe and replace it with PVC.
BTW, it's a separate small branch of cast iron waste pipe that serves a 1st floor powder room only; there's no weight resting on it from the plumbing in upper storeys of the house.
Thanks
