Can it change who and how it fights? most certainly.

What is the greatest threat to the Imperium?

Some would say Chaos, but Chaos doesn't want to destroy the galaxy, it wants to subvert and enslave the Imperium.
Necrons want to regain their lost empire, and are not averse to negotiation to some extent.
Orks......orks want to fight. Send them against another foe

Tyranids. Tyranids don't want to rule the imperium, or the galaxy. they want to consume it. that makes them the number one threat.

Therefore in order to preserve the imperium and be able to stop the slide into destruction the imperium should (in a perfect world where prejudices can be left behind)

Cease aggressive actions against eldar and tau. making alliances with these races can allow the imperium access to technology and also shift forces away from fighting these races to concentrate on bigger theats.

Withdraw from Necron owned worlds and see if possible ways of allowing the necrons their own empire is possible....alliance with necrons not out of question.

Not sure how you would re direct orks.

Unless you recognised the Eldar as being the true inheritors of the Galaxy or the Tau's Greater Good, they would not form alliances with the Imperium I don't believe. It's not just down to the Imperiums stubbornness and intolerant attitude.

The settlers on a previous Necron World do not necessarily know that they are on a Necron World, as the Necrons lay dormant underneath the surface. They would only find out if the Necrons awaken, your idea is sound but not entirely executable.

Also, I don't think there would be any way that the Imperium could allow the Necrons to make their own Empire, as as far as I know, it would be a case of the Imperium being allowed to retain their worlds. The Necron Empire was the biggest carved out in history. I could be wrong here though.
