Yes, you can carry a fuel bottle in a bidon cage, but that reduces your water carrying capacity.
Space comes at a premium when touring, so you need to make the choices that use the available space most efficiently.
+ one would need to carry the food to justify all those pots and pans taking up more space and adding to the weight
On the fuel side of things, I do a day's cooking including a cup of tea at lunch on around 40 to 50 mls of fuel per day so for a full week I only need to carry 400 mls of fuel (a small safety margin). Also I can burn wood if necessary so I don't need to rely on having sufficient fuel or be too concerned about running out. Therefore I don't think my space required for fuel carrying would be much more than your cannister approach.
That said if I am out for more than one week with no re-supply options then I will have to resort to carrying more fuel in probably that third bidon cage but then where I tour I would need to the same with canisters which are even harder to obtain.
