I think you're doing something wrong in the program, or I didn't explain it clearly enough.
Look at what comes out of a het by het cross: you get two types of offspring: mutants and 66% possible hets. With me so far?
When doing triple hets, you get the same thing with the 3 independent genes... everything that isn't showing a given mutation is 66% possible het for that mutation.
For example, say you breed your triple hets together and in your F2, you get a hypo lavender and a ghost. Just realize that the hypo lavender is only 66% POSSIBLE het for anery... both of his parents were only het for Anery, thus since he is not showing Anery, he is 66% poss het.
By the same token, the ghost is only 66% POSSIBLE het for lavender.
(If you're lost, don't proceed till you've figured out the above...)

Now, say you breed those two above together... if either one--or both of them--is not het for its "possible" trait, you will get Hypos, Hypo Lavs, and/or Ghosts, but you will never get that triple combo. How many years will you breed the two together before you figure out that it's not just bad luck, but one of them is not het?
Eventually, you would be able to get a pair of 2-mutant snakes het for the third thing, but you then have to spend 2-3 years raising them up before you can even find out if that's the one you can breed for your "triple" outcome.
Assuming you go the "possible het" route, you would be best off breeding the F2s to a known mutant or het for that other "possible" trait so you would know for sure what you are dealing with. (This adds another year to the time it's going to take you to get there... UGH!)
Meanwhile, you have the F2s that can still produce the triple morph for you, although that's a longshot, too.
But I still prefer the idea of using hypo lav x ghost and having a 1 in 16 chance
Exactly. It's not only better odds, it's a lot easier to figure out what the heck is going on.
