The parts for the stove break down as follows:  Flat aluminum panels (including the back panel with removable section): 16 oz.
Metal skewers:  3 oz.  So, the carry weight, as pictured (heaviest configuration): 1 lb. 3 oz.  This can be cut by about 2 ounces by reducing the number of skewers (I use 6 ... 4 would suffice) and using the single-piece (non-removable) back panel.

If you really wanted to go crazy reducing weight, you could remove a portion of the left and right panels (e.g., cut circular holes so the panels retain sufficient strength) in the area below the bottom panel.

One of the things I adapted (not for weight savings but more for packing considerations) is round the corners of all non-jointing ends.  This reduces the "puncture/poke" factor when handling/storing.

It would be possible to make this from material that is a bit lighter, but you couldn't go too much lighter and still retain sufficient rigidity.

BTW:  Most of the photos are "post-trip."  When I returned home, I cleaned each of the panels and buffed them with auto polish to return them to a highly reflective finish.  During use, they will pick up a certain amount of residue from being close to the fire.

You will want to test this setup before you go into the field.  I did, but I was still surprised how quickly the oven got to cooking temperature with even a smallish fire.
