Personally I think people gave up too soon on the project
The same as a multi Super. Super Pastel, Super banana, Super enchi, Super Orange dream all in one snake for example.
I think the more realistic approach is to keep everything at 1/16 odds. Breed a hypo pied to a hypo clown and make hypo double hets. Make the hypo clown pied from that. Breed an albino clown to an albino pied and make albino double hets. Make the albino clown pied. Breed albino clown pied to hypo clown pied. Make clown pied double hets. Or something like that.
With that said I currently I have 1.3 pastel triple het clown pied hypo and 1.0 pastel double het albino hypo 50% het clown and 0.1 double het albino hypo 50% het clown. Even if I don't hit on the triples, a double recessive pos het can still push the project farther.
