That's kindof like not having a sweater, and asking what color it would be if you had one. If you alter reality such that it would hit, I think you sortof have your arbitrary choice of where.
Hmm, I wonder if the poles would get hit less often than the tropics due to the distribution of asteroids being more or less in the ecliptic, or whether that's not sufficiently significant. Probably not -- I don't know of any latitude-dependent distribution of lunar craters.
