Your description of hybrids and intergrades is not quite accurate.
The term hybrid is very inclusive. It includes natural or captive crosses at the subspecies level or higher.
The term intergrade in not inclusive. It is either wild caught or offspring of w/c hybrids of subspecies.
A captive subspecies x subspecies cross is a hybrid. Since it is not wc or the offspring of wc intergrades, it is not an intergrade.
All intergrades are hybrids. All subspecies crosses are not intergrades.
I didn't quite understand the question in the original post, but if he is breeding 2 subspecies, he is in fact creating a subspecies cross hybrid, not an intergrade.

>>Breeding different species together would produce a hybrid. Whereas breeding different subspecies of the same species together produces an integrade. Often times in snakes these crossings produce offspring.
