My ideas wouldn't be much crazier.
I'd go more "out there" with Directors I'd pick, such as Jonathan Glazer.
And I'd force the Engineers and SJ to be established as two different things.
(And I'd probably have the urge to massively undermine Predators.)
As a huge Giger fan I'd make sure there'd be no more ADI fleshy Alien nonsense. The A:R Aliens would even be officially disowned as Xenomorphs.
And I'd make sure scripts are the priority above all else.
And get a redesign of the Predator keeping the head the same but change everything else, because Predators look way too human with their mask on to me.
All EU is non-canon except Alien Isolation too.
Lol I'm actually a lot crazier, this will never happen.
