I would expect that you could. Obviously MSR will have HAD to over-engineer their pot lifter to cater for mistreatment by novices, but by just how much … dunno. Interesting experiment.
I suggest either 7075 Al alloy or Ti. The 7075 will be difficult to bend as needed while avoiding cracking. 6Al4V Ti would need to be formed hot to avoid cracking, but CP Ti should be formable. Making up the dies needed if you want to ‘produce’ them would be a lot of work.
I suspect Al rivets might wear out rather quickly at the pivot. SS rivets, if you can get them, would be much better.
