we dont know that it could work if Akeno could use the pieces to revive her mother and get her parents to marry in the underworld though we dont know if it is possible given that the way that Rais said when she revived Asia was something like asking the soul to come back to the  body or something like that if you go be that it is possible if they had the original body or know were the original body was as they could recreat the body like how they planed to recreate the body of Issei after his death if they had a healthy body of the original it is possible to make them into devils.be dead or alive.
