Default Help with an oil canning panel

I have been chasing an oil can across a VW bus door for the last few evenings. The problem started with welding up a couple smalll holes in the door where aftermarket van mirrors had been installed decades ago (circles). The holes had been previous filled with bondo. The panel had an oil can which I tried to fix by shrinking at the square spot which only displaced the oil can and flattened the panel at a crowned spot. Trying again, I stretched the shrink back out out including at the holes I welded shut which I should have done at the beginning. I brought the panel up close to its original contour but still had oil canning at the square spot so I tried to shrink it again less aggressively, but got even more oil canning at the oval spots at the right. The panel is close to its original contour when I support the oil can from behind. The circle to the right can't be worked out enough because it is a snarl of weld material and hardened metal from stud gun pins. I get that I should have addressed the distortion caused by the heavy mirror and the shrinking caused by welding up the wallowed out holes and not shrunk the original oil canned area that was undamaged. I am considering cutting out the the hard spot at the right hand circle and welding in a patch so I can bring it out to contour. If I could stiffen the oil canning areas, the panel would be close enough for filler but I think it would just flatten out again and move the oil can somewhere else. I'm really stuck and have been at this for a couple of days. I did most shrinking with a mig welding attachment and some with a carbon arc torch.

I know it's hard to give advice without seeing the panel but any help would be appreciated. Many thanks for reading.
