It's kind of hard to tell in the pics just how bad the one with center damage is. But if you can weld sheetmetal, I would think the one with the corner damage might be easier. If you can get that section from another hood, cut out the bad and weld in the good piece. Being on the side where there is more rigidity, there would be less warpage from the welding. On the other hand if the one with the center damage could be hammer and dollied out then that might be easier. To make that easier you could cut out the inner structure for easier access. Then weld that back in when done.
