Do this job properly with the correct type of fittings...

Actually that is not true.

There was an adapter sold at one time that did exactly that. I think I saw
it at an online plumbing specialty store just a year or so ago. The one I
removed from service went from a 4" CO to 2" female thread.

I do however agree that cleaning out the hub and using a rubber donut or
cutting the pipe and using a Fernco is the better approach.
