To create a lucy with out using hets you would have to breed Lucy to Lucy... Not a cheap way to do it
The Lucy Makers are by definition Hets (Heterozygous) for that Lucy gene
The cheapest way to produce a Lucy would be any of the BEL makers bred to each other...
BLUE EYED:
Mojo, Lesser, Butter, ect....
Mojo X Mojo would probably be the cheapest currently
BLACK EYED:
Fire, Sulfer, Russo, ect....
If you consider the Ivory a Lucy then Yellowbelly to Yellowbelly would probably be your cheapest route to a White Snake
