I would do it if you have those snakes already, but I don't think I'd buy them for the purpose.

If you breed pied x het pied, you'll get all 100% het pieds 50% phet albinos. Hold back all the females and raise them up. By the time they are ready to breed, purchase or maybe by then you'll be able to make your own double het male, and breed him to all the females.

Even if you don't get an albino pied in the first year, with any luck you will be able to identify some females that are het albino by getting albinos in the clutch, and you already know they are all het pied.
