I've made choofer boxes before but they were from plywood and very heavy and clunky or simply old cooking oil drums cut down short
For my proposed trip to Alaska I am thinking of something similar to the Nansen choofer/cooker

But made from something smaller and perhaps thin stainless steel such as a small stock pot as LW and extra-large aluminium billies are now a tad more difficult to find
I know there are excellent modern clones available but I don't think I will have the funds needed for custom made CF stuff.
Only for a 2-Up trip so I'm happy to use my existing pots, either the MSR or the TOAKS and most likely a combination
One thought I've had is to modify a Bundt pan with side handles to use as a snow-melter

or an Angel cake tin but these are usually 2 piece and I find it difficult to solder aluminium and silicon may not take the prolonged heat

A single piece Angel cake tin might work well
The idea behind the Nansen cooker is total shelter from the wind and to capture as much heat from your fuel as possible, any excess cooker weight being easily made up with the weight of fuel saved and melting snow takes a lot of fuel
Other ideas that have crossed my mind are thin aluminium sheets folding on short piano hinges like an old fashioned collapsible meat safe.
The MSR XKG_EX would be sitting on a ply and aluminium base which would probably be insulated with CCF or similar or it would sit on top of a purpose made sledding box which would protect the stove during the day and give added height for cooking
