Interesting theory. I would say that what sustains Tzeench is thought itself. All races in the Galaxy make plans and think, exept the Orks, that would mean that scheming or the flow of thought might sustain Tzeench. And that, as you said, could also be supplemented by the unstable nature of the Warp. Perhaps, as Slaneesh was created by the Eldar, Tzeench might have been created in some way by The Old Ones, making it the second oldest Chaos god, followed by Khorne.

Humanity has never conquered the Galaxy, it has merely become widespread. Conquering something means eliminating all opposition, and ruling unchallenged. The Galaxy will awlays be contested by atleast a few species ,such as the Orks, and thus unless they are made nothing more than a mild annoyance, then the Galaxy is not conquered.

Normal Humans would barely have survived the living in the Milky Way in the first place, let alone conquer it. Only with supreme, higher guidence, such as that provided by god-like superhumans, can a place as dangerous as the Galaxy be contested.

Humanity will survive the coming storms. The imperium will not crumble overnight. It will take decades. And when the Golden Throne finally stops functioning, for one reason or another, something will happen. About the Astronomican. It is like a lighthouse, fueled by the life energy of psykers. Perhaps if the GT stops, the Astronimican will still work, and will still glow, but might require even more psykers to fuel. As for Mars, they most likely do have an STG template. If during that destruction it is uncovered, it would be extremely beneficial for the Imperium, also Mars is not an easy plane to destroy in the first place, and the Void Dragon will be weakend if it manages to escape, so it is unknown if it will flee or start a rampage.

And lets not forget about intervention from The Old Ones, they remain an unknown factor in all of this.
