Aluminum is a bit tricky to work with but from what I can see there, Mitchell, I’d first attempt to repair and straighten that door skin and resort to installing a new one if the attempt fails. I suggest taking the door off the car and drilling out the rivets securing the internal panels leaving only the skin, hinge panel and shut panel attached. Next step is to hammer out the stretch using a leather wrapped wooden mallet or slapper, getting it as smooth as possible, though it will present a heck of a bulge. Tig weld those small holes closed and grind them flush on both sides. What’s left is to shrink the aluminum skin down to flat using a large shrinking disc and 6000 rpm body grinder - higher rpm will badly spall the metal. As it is, you need to lubricate the metal well before applying the disc and for that I use liquid hand soap.
Shrinking aluminum isn’t as straightforward as shrinking steel because there’s no colour change. The liquid soap in fact turns black from the minute amount of metal removed during the shrinking process. What you will see as you go along is the aluminum expanding slightly, indicating that it’s heated up sufficiently to shrink - hit it quickly with a spray of soapy water, wipe clean, reapply the hand soap and repeat. It will take many applications to get to flat.
