I guess so. But of course the key weakness of the nids is one of their greatest strengths; they are united without sentience of their own by the hive mind. True this makes them invulnerable to phsycic attack and means that they act like a colony of ants all working towards the same purpose, but if you kill or cut the nids off from the hive mind they turn into animals and run away or start fighting amongst each other, or in some cases they just die.

Killing the hive mind is nigh on impossible since it is heavily protected not to mention we're not 100 percent sure where it is but cutting the link is much more do able.

But as for the island theory that would make sense wouldn't it? Since the ruinous powers rely on sentient life to sustain them they could only survive in small patches. But we know the Tyranids lived out in the void between galaxies for who knows how long so why not something which lives there permenatly? Chaos gods would form naturally as a result of the evil which is always created by sentience due to the fact that nothing is perfect. That in turn would lead to warp distruption a voila! An independent group of chaos entities.

But that would be even more unlikely to happen than the way it happened in the Milky Way, but when you consider the fact that the universes go on forever it must happen eventually. That's logic! I think.
