THEORY: How Shaw might be alive

So I came up with this theory while I was browsing through Matt Hatton's Instagram. In some of his posts regarding Shaw, he mentioned something like David cloning Shaw (just his theory). This got me into thinking, that Shaw isn't dead, and might actually still be alive. Here's how I imagined the scenario before AC:
-David and Shaw leave LV-223 in Juggernaut. Before Shaw goes to hypersleep, she and David spend some time together, developing a friendship. David teaches her
Engineer language and how to operate juggernaut. And then when she goes to hypersleep, David over time grows more hatred towards the Engineers.
-When they arrived on Planet 4 you know what happened, David unleashed the pathogen, killing all Engineers on the plaza that were welcoming them.
-Then something happened with the docking ship and Shaw and David's juggernaut that caused both ships to crash.
-David awakened Shaw from hypersleep after idk how many months (waiting for the pathogen to become dormant). He explained to her that the pathogen was accidentally unleashed and in confusion, the ship crashed.
-They both settled inside of the citadel. David spent most of the time providing Shaw with food. He and Shaw both began studying Planet 4's fauna and flora.
-David then became interested after finding out what the pathogen is capable of doing, besides killing hosts. So he started doing genetic experimentation using things he found and managed to salvage. Doing all that behind Shaw's back.
-Shaw soon became suspicious of him. And soon she found out after going into the crashed Juggernaut and activating the holographic recording that it was him who unleashed the pathogen. Upset by this, she sent a distress beacon and later confronted David about it.
-David admitted her that and also revealed that he spiked the goo into Holloway's drink. He also revealed what he's been doing behind her back and his evil plan.
-Infuriated by the reveal, Shaw tried to escape him but David stood in her way. Shaw fought back but David stabbed her in the stomach, wounding her. He also told
her that he doesn't' want to kill her because he has plans for her. Shaw somehow managed to stab him with something which gave her enough time to run away.
-Outside the city, she eventually collapsed and lost consciousness because of the wound.
-Luckily, she was found by a couple of Engineers and taken somewhere underground where a large majority of Engineers (men, women, children, elders etc) who managed to escape settled there. They also healed her wounds.
-Shaw explained to them what actually happened and they told her that there's one remaining ship left in the hangar that they could use to leave the planet, only if they knew how to fly it. Luckily Shaw knew how to operate it. She also warned them about David's plans.
-In meantime, David was finishing working on some of his mutated experiments. I guess some are the Neomorphs spawned from the Engineers/animals and other mutated monstrosities. David unleashed them on Shaw and the remaining Engineers.
-Shaw and the Engineers arrived and fought David's creatures.
-Despite some losses, they managed to kill all of David's creatures and get to the last remaining Juggernaut in the hangar and leave the planet. Leaving David alone on the planet.
-David, heartbroken that Shaw left him, still continued with his experimentations using the remains of his creatures and the Engineers that were killed in the battle.
He also had Shaw's blood (he gained from stabbing her) which he used to try to clone her, but without success. Instead, he used Shaw's cloned corpses for his experimentations.
