I also do bikepacking (i.e. off-road bike touring) and lessening bulk is just as much a challenge as cutting weight. Once you get above 20-25 litres in volume then it starts getting a bit cumbersome and affects the bike's handling - I'll have around 15 litres capacity for a UK summer two night trip including food and fuel - so meths stove and its paraphernalia packed into something like a 400 or 650ml mug tends to be the usual choice.
Had a little lol at that, just done my first bikepack, 54l panniers and it was a struggle to get it into that, still, lessons learned as what to take or not
