Kinshiki noted Momoshiki must do to him what he did to his guardian aka use his rinnegan to consume himself. That explains his abnormal giant appearance, which would be a result of consuming his guardians chakra and transforming. My guess is that the transformation lead to him growing a horn and covering his forhead Rinnegan.

Bloody Mist Sword Art: Bone Mutilation disrupts the chakra pathway system, making Kinshiki unable to absorb it and Kurotsuchi's Lava Release. The only time he had a chance to absorb ninjutsu was when he was being restrained by Shikamaru's shadow, but Momoshiki beat him to the punch.
