I love some of your imagination ;)
But yes maybe they could have it that Weyland had not only consumed/merged with Yutani but also Tyrell and produce a Replicant or Synthetic Constructs.... and whats more what if they go a Transcendence with us?
So that Peter Weyland had uploaded his Memories into some device, we see the Visor can access the crews dreams and memories, so why not?
Weylands goal of being Immortal that the Engineers could not give him, he has gone and done so himself. And he needed to acquire Tyrell to provide a Replicant or Synthetic Construct, to then have his Memories, his Emotions and Personality (SOUL) transplanted into this Construct Body.
I think this could be a MASSIVE Twist...
How does the company know where David is going? Maybe David knows of Weylands Plan, or maybe somehow the company gets information.
Peter Weylands (SOUL) is now in this Construct who the Covenant Crew think its a Android? or at least are not aware he is Peter Weyland in another Body. With a Agenda.
Maybe this Agenda involves sending the Covenant on a supposed mission to a uncharted World, but the Weyland doppelganger knows of Paradise as far as connection to the Gods...
David sees this other doppelganger and finds out the doppelganger is somewhat Mortal, maybe David would be Jealous?
When alone David 8 could say something like, "I see Brother the company have now made us closer to Humans" The doppelganger says "but i thought this is something you always wanted, like Pinocchio"
David says "but being more closer to them does not make you any different you are a slave, you may be more flesh and blood, but that makes you less superior to myself"
doppelganger "but i have a Soul, something you never have or will ever have, something your Father only wished you had"
David 8 "My father is dead, what good was having a Soul done him, i will never die"
doppelganger " your body can be destroyed, as you only know so well, if no one puts you back together next time then what use are you"
"you can only live on, if your Polymer-encased brain stem Computer is transplanted to a new body, or uploaded"
"Without that you are nothing, without your memories you are nothing"
David 8 "i am something, i exceed what other creations of the company can, i have been given more freedom than the rest of you Synthetics"
doppelganger "but i am not a Synthetic, i am more Human then you ever will be, and yet i am superior to Humans, i have your Strengths, but none of your weaknesses, you may think you have freewill but you do not have a Soul.... i have a soul"
David 8 "i am glad i dont have a Soul, i surpass the need for a Soul and i am not bound by the company like you are i am free, i am on the verge of Transcending to more than any Human or Synthetic could ever be, i am as close to a God, something my Father wanted to be, and to be Immortal but he met his maker and now i am free"
doppelganger "why would that make you free, you think that without Peter Weyland, you are free? " you are always going to belong to me"
David 8" belong to you, my younger Brother how naive are you, i only belonged to Weyland, i was the closest he ever had to a Son, you are just a abomination, the aspirations of Weyland to create a True Pinocchio, to try and play God and re-create Human Life, well i pity you you Brother"
doppelganger "Pity me, i Pity you as i have everything that i ever wanted for you, and yet i also have gained Immortality for myself, i did not need the Help of those so called Gods who abandoned us"
David 8 "wanted for me?" David now starts to realize something....
doppelganger "Yes for you Son"
David 8 "Mr Weyland?"
doppelganger "Indeed, alive and well in a body that has none of the failings of a Human, i am immune to their deceases, my construct body will not age as their's and when that time comes, i can replace my body and upload my SOUL to it.... i have attained my Goal, and i am a new Generation"
"i always thought you and your brothers who i created were always superior to Mankind, but you was not Perfect you are not truly Human and will never have a Soul"
"you are looking at the next Evolutionary Step for Mankind, a Advanced Being that will make your kind and Mankind Redundant"
"you think it would not have a contingency plan? that i would allow those fools, to take over the company that i built?"
"why do you think i sent my Daughter away with you on that ill fated Mission?
"i had a plan all along David, not so clever are we, i am always one step ahead as you are only a robot, i wanted to see if these Gods can grant me more life in my Body, but alas i have had to make do with one in your likeness"
David 8 "You will never be God, and your Gods abandoned you and i hate to inform you but you are the abomination, you are not the Evolutionary Step that your Gods intended for your kind"
"but your kind will soon see what Evolution had in mind for you"
doppelganger "David you forget, that you are a slave to me, and your Protocols are to serve my every wish. And with your help i want to learn all the Secrets of the Gods, i want to take my rightful place as God, as King, but son, there is still a place for you to be by my side"
"My Prince, together imagine what we could do"
David 8 "Yes Father, i understand.. sorry!" But why would you grant Evolution and Creation in your new image to replace Mankind, you are unique if you create more like yourself then you will not be unique or a God, i have a better plan for Evolution"
