Pat,
It doesn't sound like you have enough of an issue to warrant drilling out all of the welds at the rear edge of your outer coal and the inner cowl in order to twist your hinge pillar back into place.
What you may want to try is to remove the door and put a long pipe on the hinge straps and leverage the the hinge inboard a smidge.
This will bend the hinge pocket without distorting your cowl. It won't move the hinges piller, but it may well take they springiness out of the door closure. It doesn't sound like its going to take much movement of the hinge pockets to solve your problem.
