The body that was weak was the current host body, you are completely ignoring context. You also seem to forget that Orochimaru is currently Kabuto but better because he used a White Zetsu to perfectly incorporate Hashi's DNA into himself when he took over its body. If anybody can take in Madara's DNA in addition to that and get the Rinnean then that is Orochimaru.

"In his quest to gain immortality and a perfect body, Orochimaru has made a number of modifications to his body over the years, referred to as the Power of the White Snake. With it, he can heal and regenerate from varying lengths of damage in fairly short periods of time. For more grievous injuries, like bisection, he can reconnect himself using snakes or shed his skin to regurgitate a new body, free from all damage. Orochimaru's modifications have also allowed him to manipulate the shape of his body for greater manoeuvrability, and enhanced his physical durability enough to endure multiple enhanced punches from the already-super strong Tsunade.[46] Orochimaru&#039;s True Form

Orochimaru's true form after many experiments.

Orochimaru's modifications have resulted in his true form taking on the appearance of a giant white snake, which is composed of many smaller snakes that can be used to attack the opponent. The blood released by killing the snakes is poisonous, evaporating into the air and paralysing anyone who inhales it. This form also enables Orochimaru to use his Living Corpse Reincarnation, his main method of immortality. It allows him to transfer his soul into a new body by swallowing that person whole and absorbing their consciousness, thereby gaining control of their body. This can only be used once every three years, as Orochimaru's current body begins to reject him and forces him to find a new host. The souls of the bodies he has taken remain in Orochimaru's subconscious and he can modify his body as he sees fit.

After Sasuke reconstituted his body from Kabuto's highly modified flesh, he also obtained access to the unique skills and Kekkei Genkai of the Sound Five, including Sakon and Ukon's Kekkei Genkai, Jūgo's Clan's Kekkei Genkai, and Kimimaro's Shikotsumyaku. He also later gains the ability of Hashirama Senju after taking over the body of a White Zetsu clone, which was modified with Hashirama's DNA; this included their accelerated healing and no need of nourishment.[47] "
