Another reason the old ones couldn't have made the tyranids is that the tyranids and the necrons are capable of coexisting. the tyranids turn meat into tyranid, and the necrons turn everything into necron. even if the tyranids won the galactic war and left the galaxy as a barren shell of its former glory, they are almost guaranteed to miss more than a few tombs, and thanks to canoptek scarabs, the necrons can replenish their strength and feed their gods using the inorganic leftovers. if the hive mind and the overlords got in touch, an alliance could even be arranged, as the biomass consumed by the tyranids is nothing to the mass of the leftovers. both are pretty much immortal, and a multiversal conquest is a possibility given that the necron scientists can get enough energy to breach the universe.
