Another idea is to use a rectangular 1.n litre food container/lunchbox and store the packed trangia in it side on.... As its probably easier to find such shaped containers in a suitable size, I wish I had thought of this on the school/university mountain/hill walking clubs long ago....
I decided the large frylid diameter bowls were suboptimal...I have found following Tesco rectangular 1.3 litre food container/lunchbox and the trangia will fit neatly in it, on its side: https://www.tesco.com/groceries/en-GB/products/308611261 The polypropylene base is approx 80 grams and the item is only 2 pounds sterling (I bought one)
