Even replacing an 0805 is a pretty significant challenge. I have no idea how people do BGAs with anything but a pick and place.
Plus, without x-rays, how do you know you got it right? There's a lot of ways something can have a weak joint that isn't immediately noticeable. And, unless you have CNC equipment the result is more art than science, the quality depends largely on your hands.
I wouldn't trust a device that had been repaired by anyone but an experienced pro, seeing as how these devices(along with phones) are the cornerstones of modern life.

(Which, admittedly, is rare, but you have to take the liability on yourself every time). Something like that is entirely non-feasible for mass manufacturing of parts with any guarantee of quality though.
