I understand your point about emulating their techniques, but today we could do better. Whether the Egyptian pyramids were made with hewn stone, poured concrete or clay and straw bricks, we have much better capabilities today.

We have access to a wider variety of materials (marble, granite, steel, concrete) and we have heavy machinery.
