The question itself is not posed correctly. It should be what would happen After chaos and any xenos reach Terra.

The necrons starships can phase, meaning they are almolst undetectable, and can probably do a peek-a-boo and even land on Terra itself.

It is a matter of time before the Tyranids get there.

The 13th black crusade is not finished and Abaddon has a few more cards left to play.

The Orks scenario is simply too unlikely to happen

Dark Eldar can probably reach Terra by sheer speed and a suprised attack, but then would have to flee just as fast because they cannot even scratch the defences of Terra

If all Eldar Craftworlds form an armada, they can even beat any aerial defences or fleets over terra, but the Eldar have no reason to attack Terra, and will not do it

The Tau are currently not strong enought for something like that, and considering the threats they have to deal with, or that if The Imperium musters enought of a force can even exterminate them, despite the horrendous cost of it. If the Tau were left unchecked, and continue to expand and advance as they do, then Maybe in a thousand years or so.
