Orochimaru is a huge unknown, but it seems to me that the whole point of the Shin program was to perfect Kabuto's jutsu. Considering his appearance is different since the 4th war, he clearly did switch bodies from a Zetsu. Couple that with him clearly possessing at least one Shin body after Shin's defection and Orochimaru making several Mitsuki, i think it's virtually guaranteed that Orochimaru himself possesses an artificial Mitsuki body of extremely high grade.
