Actually, it would by default reproduce the "accuracy of the cardinal alignment seen at Giza". The "cardinal alignment" is simply an artifact of the Earth's rotation. It will always give true rotational north no matter what the stars say or how they shift.
Another interesting thought is that they might be aligned to the rising sun at a certain date... perhaps an important festival. Again, this would be more likely (and is a very common technique throughout the world) and more culturally significant than the north.
