Ridley Scott talks about replacing the alien

That kind of depends if he talks about getting a new monster or he will replace it with androids. Getting new monsters can be alright, I liked the Neomorph and the Squid was OK. Maybe it could work without the Giger thing, I don't know. Replacing it will be difficult but I do not want another Bladerunner/AC where we will see androids as the enemy, screw that. His obsession with David tells me that there is a risk that it is the way that he might go and if so I am out of here unless they make better human characters. It depends on how you treat them, the Xeno was there for some seconds and then it got stuck in a crane, that was lame but if you get new monsters and use them sparingly and keep them in the dark it could work because then we can use our imagination but then we need characters to care for. Unfortunately they have failed with the characters this far (in general P and AC since we talk about the prequels).

Maybe they could try would be to make the Engineers scary as F, then they could replace the Xeno as the main threat. For that to work we need to know a bit why they are mad at humans but they should also not be totally obvious since there needs to be some mystery for it to work. The Xeno worked since we didn't know a lot about it so that should be how they write the Engineers also. Call it a silly idea if you want but I think that this could work if they write them really really well. Let's see how this will develop

The mural could be better used if there will be a next movie since they were just shown briefly in Prometheus. They could take that and develop it since I think that the basic idea is interesting. Unfortunately I can not support the idea that the ship made the eggs, it is an interesting idea to write about in a fairy-tale but it won't work in a movie at least not for me.

About effing things up, they already did enough damage the way it is with Alien Covenant. It is without a doubt one of the worst Alien movies this far.

Critters5: I would rather have that then both AC and Prometheus. The thing is that we need well done human characters and make them fit in somewhere in the story too.

IgnorantGuy: As far as David being overthrown by the Xeno yes it is kind of obvious, I am not interested in that. I do not care about the adventures of David because that is not why I watch alien movies. To me it has always been about well written human characters that get into situations that they are not well prepared for. F the androids and the themes if I can not care about the characters.
