No Chaos god means no corruption. Imperium will have all the Age of Technology marvels, STC included +20000 addictional years of tech advancements. All Legions counting millions Astartes (or maybe better) each with weapons and armors outscaling everything else in the known universe. And each one with a loyal Primarch at the head, sided with advanced AI machines of war to throw at everyone who dares to bother. And all of  that can travel instantly thnx to the webway made by the still healthy Empeor.

Even Eldars at their finest will have work to do dealing with an Imperium like this. But they probably would not allow this considering that no near-extinction event would strike Eldars without Chaos Gods (As Sanguinor says).
