[WH40K] If the Emperor had managed to complete his Webway Project before being put on the Golden Throne, would things have turned out any better for Humanity?

The reason the Emperor *has* to sit on the Throne is because a massive hole got ripped into the Human Webway, and the Throne is the only thing keeping the Warp from spilling out. If the Webway had been complete, the Throne would just be a life-support system. Maybe without the extra strain of keeping *literal Hell from spilling through*, some of the Emperor's vast power could go towards healing himself, but maybe not; Horus had some pretty nasty weapons.

Also, the Imperium would kick everyone's ass with near-instantaneous intra-galactic travel.
