In terms of food security - it is probably easier to transfer the skills necessary to raise caribou and ptarmigan so that the locals can eat the meat their bodies are designed for than it is to teach their bodies how to eat Coco Puffs.
Importing, or even cultivating, carbohydrates that the caribou, the geese and ptarmigan, or even some fish can exploit and convert into food that the Inuit need, to my mind, makes a lot of sense.
There is a lot of literature and practical knowledge available on domesticating animals like elk, reindeer, deer generally, geese, ducks, salmon and sheep. The musk ox is just a really big sheep.
