1) Can you provide a photo of the animal’s ventrals? That would be a big help in "identifying" the snake.
2) I am not saying you have a hybrid, BUT, there are several markers on the animal that suggest it may be a hybrid. The head pattern is not "correct" nor are the dorsal blotches. Many of the blotches split and appear to be "sliding" off the corn. They are the ones that form the "Mickey Mouse" heads That is a definite Emoryi trait.
D) MOST corns are not very banded unless they are selectively bred for that trait or unless they have emoryi or some other species in them. Since you have no information on the genetics, then it is hard to say which this is, but my suspicion is an emoryi influence.
My current guess is to say it is an emoryi/corn cross likely from the Candy Cane variety (as you suggested). I reserve the right to change my opinion after seeing pics of the belly. My hunch is that the belly will be patterned very much like an Emoryi and not a corn.
