I've never been convinced the character in the third film is even human, mainly because sending a guy with robotics/software expertise on a specimen retrieval mission for the biological warfare division... It never made sense to me then and it doesn't make sense to me now. Whereas something which can have its data erased for plausible deniability totally fits WY's MO.
That said...
This story is either going to have to do a lot of mental gymnastics to work or is going to feel lazy and superficial. Like, why even bother rebuilding Bishop's physical shell? Just copy the data over. And, as was pointed out, what would Bishop even have to offer?
Alright, so... Let's be generous and assume, in addition to spending some time on the facehugger corpse, Bishop would also have access to all the colony laboratory stuff which went on before he got there (which, judging by Ripley's reaction when he goes over it, didn't offer any more understanding than her report included). But it's not like the place is super-advanced. They would have had something at least on par with the Nostromo's 'auto-doc' X-ray thing. Presumably what allowed them to figure out the facehuggers were attempting "embyo implantation" and that removing it from one of them occured before that took place. But what else?
It would have been somewhere industrial-type accidents and maybe exposure to unsafe chemicals/toxic waste could be analysed, diagnosed and treated (at least for however long it would take for a signal to be sent to/received from the closest outpost and a medical ship to cruise out). It might have had an ability to do DNA analysis? Maybe...? Although, even that's a stretch. Why would they even require that ability?
But let's say they somehow gained DNA data. Aside from that, there wouldn't be much else. And it still wouldn't necessitate rebuilding the entire robot, just copying files over.
Apone's relative is... Needless. Fan service has its place and this isn't it.
And why bother with the nonsensical 'dog catcher' costumes? How would they be of any use in getting ahold of Bishop? Or are these meant to just be personnel from the same department? In which case, you're sending staff/thugs trained in biological specimen retrieval after a robot? What?
Maybe the reason this guy is no long with Weyland-Yutani is because he got fired for wasting resources and general ineptitude.
Major odds there'll be an excuse for him and Original Flavour Bishop to verbally negotiate for the data, just to have him say, "Think of all we could learn from it."
