ALIEN 5: Resurect? or Purge?

It will also be interesting to see how he will make so much progress in so little time with only 2 face hugger embryos and no lab equipment (unless he can magically make-shift what is on-board). 

Thats a good point, which shows the writing for Alien Covenant was flawed, in many ways...I may consider taking Alien Covenant and doing a Re-write myself, i did start with the same with Prometheus but abandoned it however...

So we do need to look at the events from Alien Covenant to Alien, we have about (maximum) 18 years before we get to Alien, if David created the Xenomorph so lets say if Dr Shaw decided to leave David in Two Pieces at the End of Prometheus or even just recovered his head and tossed it into the Flames of some of the Prometheus Wreckage... then we would not have no Xenomorph Eggs on the Derelict?

If indeed David is the creator, so here is something else to consider... David must be able to increase the number of Eggs to Thousands and for them to get onto a Engineer Ship, all within 17-18 years, with just TWO Face Hugger Embryos.

It appears David will be going to Origae-6 which will take 7.5 years and so by the time David arrives at Origae-6 if we assume he uses the Covenant, then we only had a Period of 10 years for Thousands of his Creations to be ready in Egg Form and end up on LV-426 which we can safely assume is no where near Origae-6

We can assume the Covenant Ship has Laboratories, Med Bays etc, and so maybe one way could be if David was to Tinker and Experiment with one Embryo to then extracts its DNA and Splice it with the Human (we assume) Embryos?  But having some Black Goo would make this Task easier, maybe he snuck some on the ship with him?  But its a bit of a stretch, but then so was him having time to make himself look like Walter and Obtain those Face Hugger Embryos.  I am sure while he was in his Workshop it would have taken but a minute longer maybe less to get a Black Goo Glass Vial.

But then what is stopping David from going to Planet 4 again to pick up some more Black Goo and/or Eggs/Embryos?

The only other option would be one of...

A) The Xenomorph Procreation, does his creations Egg Morph, or does one become a Queen?

B) The Engineers arrive and take Davids few Creations to LV-223 where they begin to Mass Produce them?

anything that retcons alien 3 is bad for the franchise in my opinion. people have to realize that alien 3 probably expanded the universe more than any other film in the series. if they ignore alien 3, remember that the xenomorph dose not take the form of its host. it will always look the same. a humanoid. this would then kill atleast 95% of the comics and toy parts of the franchise.

Totally Agree.....

I think a Alien 5 would be a good idea down the line, but it would have to be something NEW, and Blomkamps ideas had some interesting things to explore, however introducing the Queen and Ripley again is not one that should be followed.

"The Engineers arrive and take Davids few Creations to LV-223 where they begin to Mass Produce them?"

This, if they will explain that the SJ is an Engineer, then at least they will explain why there are so many eggs on the Derelict. I would probably prefer that the SJ is a long distant relative to the Engineers though which could explain the difference in size between them.

Timmy: I don't want them to retcon Alien 3 either, I would be disappointed if they did so. They better not do that being that they have done enough damage with Prometheus and Alien Covenant.

I agree that Alien 5 should resurrected if it reconciles to Prometheus. The avenues to explore explained above are fertile ground. I really like the idea of following the evolution of the Queen shown in Aliens. I wasn't really excited about the queen until David said he found his at the end of Alien: Covenant.
