Ah, so you're thinking of incorporating the Mothership Zeta stuff in there? Interesting. We can always use a few more aliens.

The idea is that the debris from the ship you destroy was far too big to have all burnt up in orbit and large sections of it crash land in Canada, which is how certain factions have risen into power, and why both BoS and the Enclave are having a bitch fit over it. Of course, the most powerful stuff it either undiscovered, or damaged (at point) to be repaired to a fully operable state.
