I would build a router jig that would cut a side and an end. Cut the door as Loren said and put on new trim. Put in a larger panel if necessary then trim it out. You need some glue and a small nail gun that will not penetrate the door and come out on the back. Take the doors one at a time, place them in the job and router the bad off. Turn the door 180 degrees and do it again. You can make the jug large enough to do all sizes involved. Last time I bought doors like this they were $56 and they were no wood. I think you can do it cheaper. I would sand any paint before I put the trim on. That way you will get rid of the torn pain edges without a lot of work near the new trim.
