I don't believe any of the dwarf locality boas have albino as a morph so you would have to find someone producing "mutts". I've only ever seen one ad for a snake that was even close to what you want, and that was for Tarahumara's that had been crossed with a kahl albino so the offspring were half Tarahumara het Kahl.
You could try Abomination Boas, that's the only breeder I know of mixing morphs into locality lines.
