If I may... You make some assumptions April that are a little too overgeneralized. There is actually a decent likelihood of compatibility in Albino mutations as there are only a few genes that can be mutated to get the phenotype. So it is entirely possible to get an Albino hybrid in the F1 breeding. And very specifically, if you are breeding T-neg Albinos from both species together you are absolutely guaranteed to get Albino hybrids. This was done with BurmBalls, a het Albino burm was bred to a het Albino ball and generated a visual. I have also heard a rumour that someone has made an Albino Carpall from a visual x het cross.
The "grey" areas here would arise in situations where you have T-pos Albino types that are so extreme as to appear T-neg, like the Kahl and Sharpe boas you mentioned or the three different "white"-type Albinos in retics. If you were to breed one of these to a true T-neg you would not get a visual
