I doubt that the ornamental plant industry would use an expensive hybrid such as Haley's Comet for grafting. You could also consider the genus Cereus. There are 11 known unique species in Hylocereus, 9 in Cereus, and 8 in Selinicereus.
Selenicereus megalanthus has been genetically reclassified as a synonym of Hylocereus megalanthus.
