I dont think it will work like that. Kronos and Luke were joined physically, as in Kronos was using Luke's body to bring himself back. When Kronos was about to break free of Luke, he was going to burn his body away and take his true form. However, Luke killed himself (and Kronos as well in a way) and his soul went to the underworld while his body remained on earth. Kronos has no power over the soul, only the body so the idea of a part of Kronos remaining in Luke's body seems unlikely
