Yeah, I keep toying with cutting up an old aluminum pot or scout mess kit. The problem I run into is that to get lighter than the trangia sets, I think you need to go to something like aluminum flashing and then how do you support the pot? (Trangia does by hanging the pot from the windscreen.) If you go with heavier aluminum, then you probably end up with the same weight as the Trangia in a stove that is not as effecient. Cheaper, but not as good.
