Certainly would be interesting, but then doing a Alien movie on Earth with Aliens, would just bring back memories of AVPR lol
I think it would have been the Logical Sequel to Alien Resurection however if they did a direct sequel with Miss Weaver as Ripley 8 then logically it would have had to bring in the Xenomorph again.
And so landscapes like this would have worked but in some state of ruin as Earth did look like it was in a state of War, well after some kind of massive War.
But as far as how the Earth would look around say 2150-2200 Time line indeed i can surely see those concepts fitting the look and feel.
The universe is more than just Ripley and Xenomorphs though, and so it would be interested to see a Spin Off thats not connected, but then its if we ever would get such a thing... The Alien Covenant: Origins Book looks to touch up on and take this kind of route however so that could be a interesting read.
