How about having them examine Yamato to know what Orochimaru did to qualify his body to survive through the injection. Then they would build up on that for many years until they reach the perfect way to inject the DNA. Despite all that, they needed an individual with exceptional life force to sustain his form and body and not be overwhelmed by the DNA, despite the severe modifications done to his body.
