Multiple personality..?

We know now that it is indeed David pretending to be Walter, and I've heard differing theories as to how the switch took place, ie either David cutting off his own hand so as to look like Walter, or David downloading himself into Walter's body and using it therein. But watching Fassbender during the xeno chase scene it's almost like he's both David and Walter at the same time. He seems conflicted, which admittedly could also be due to David having to 'sacrifice' one of his xeno's for the longer-term goal of further creation. But now I'm wondering... Could it be that David did indeed try and download himself into Walter's body, expecting a full over-write; but what actually happened was instead a merging of the two? The same way when moving files on a pc you sometimes get asked whether to over-write or merge? This would make for an interesting set-up - a David/Walter split-personality AI. It would explain some of his seeming-self-conflict aboard the Covenant and also how he skips from Walter to David re codes etc as he is in fact both of them?
"Is that a question Sir?"
