Technically you wouldn't be producing a Hybrid by breeding two getula subspecies together. In a sense of genetics its kinda like a person from Europe breeding with a person from Asia. If that happens the children look different from each of the parents, but are still able to breed.

As for the offspring from your crossed clutch, you can certainly get rid of them to new owners; probably not for money. Just realize that whoever takes one of the animals then becomes responsible for never letting it react with the natural world, because as we know many new snake owners tend to release what they don't want into the wild. That is why it is best not to breed them.
