another thing that you could try with the door edge:
break the inner and outer door apart at the edge.
move your inner door (shorten) to where you want it.
leave about a 1/4 to 1/2 inch of the old door past the inner door edge. trim off the rest.
hammer and dolley your new edge around the inner door
spot weld back together.

there might be issues when you gert to the compound curves, you might need to make little cuts ando them a couple inches at a time.

the other method you could use, is to trim the skin off right on the edge of the inner door.
spot weld the skin to the inner door.
then use round rod to create a new door edge.(this is the same method that you could use to fix a bad door gap tat you can't adjust out.)
