The hate for Etihad is strong I see.
This would be a colossal waste of $400 - 600M. All for a few games.
Etihad is a great viewing ground, the infrastructure of the stadium is fine. Spruce it up a bit, sure. Burn it to the ground, no. Opaque roof maybe, new seats, upgrade the catering, new screens etc
Etihad doesn't disconnect the docklands from the city. The huge mass of rail lines do that just fine by themselves.
