Multi use is always nice. But if you are using your Klean Kanteens to store water and cook. Where do you put the water when you need the Klean Kanteens to cook?
I really like the beer can pot/alky stove combo because they weigh next to nothing and the pot can be used as a coffee cup.
In this picture the blue cup and Ti pot is replaced with the beer can pot/coffee mug.
Another good duel purpose kitchen idea is a wood burning stove that can also use an alky stove. The woodstove also is a pot stand and wind screen.
I have a hobo stove that's supposed to be a wood stove too, but haven't really tried, but it makes a great windscreen/pot stand (way better than the one the Trangia came with.
And in terms of water, put it in the bottle that I was drinking from as I rode to my camp spot/drink it.
