Is this a common practice?

So, since my boy is a spinner blast (spider, pastel, pin stripe) I got my girl from an unrelated breeder in another state, an enchee firefly, (pastel, fire, enchee) to eventually breed to him. Will i be able to water down the spider gene. I would also love to pick up a coral glow female from an unrelated breeder, to give me enough of genetics to work with. Is this a good plan of action, since my house space is limited. As an retired dog breeder, i know the challenges of line breeding, and maintaining the best traits during outcrossing. In dogs any breeding you do using dogs related closer then cousins is in-breeding, line -breeding is cousins or niece, or nephew to aunt or uncle, and a out cross is no relation to any dog for at least 3 generations. The accepted practise is 1 line breed to 2 outcrosses, then a line breed then 2 out crosses, but this is in dogs not really nessecery in snakes, i guess, unless you want to bury a bad trait, like a wobble. Am i being over causious or is this a good practise, any suggestions would be helpful and opinions weighed carefully.

There is no watering. A snake is either heterozygous for spider or it is not. As far as we know there is no surviving homo version. The wobble is linked to the visual gene. No one has had any success reducing wobble through breeding. I can guarantee that any spider will wobble if put under enough stress. There are many threads on here about this. Understand all things spider before you breed them.
