Wayne's idea of a porta-power or other type of jack could push the hinge pocket and pillar forward. Be careful to spread the load against the back of the door opening and go real slow. You don't want to kink the cowl panel. The other option is a 2x4 laid flat on the hinge pillar and a BFH. But that can go bad pretty quickly if you swing too hard. Again, go slow.
Once something is fully welded in, planishing doesn't move things very much if at all.
Lay a straightedge against the pillar to see where it needs to move. I believe it should be flat from the top of the upper hinge all the way to the bottom of the pillar. You might need to cut it where you welded it where it wraps forward to give it some flexibility to line up.
