If you have access to a vinyl cutter, that would be the way to go for this. 1/32 seems a bit small, but I'm not really sure. We tend to keep our walls at least 1/4, though for these parts structural integrity is an issue too. As far as other methods, no. Water-jetting will give you the cleaner edge than plasma, and a more reliably straight cut. With plasma, the edges are jagged, and may accidentally cut through a 1/32 wall. I think the wall thickness may be dependent on the precision of your water-jet, so I'd look for those specs if you can find them.
