All the posts I've seen were about making a barred or cuckoo araucana. People answering have spoken about ameraucanas, but not the original poster (I think). There has been confusion as to whether the goal is barred or cuckoo.
I do find it difficult that she or he has created numerous threads on the same topic on several forums. And I don't believe sufficient time has been allowed for some of the breeders to get back--many people do not check their email or messages multiple times per day--I know people who only check once a week. And some folks don't do email at all. When multiple breeders are working on a similar project, I believe they need to be in contact with each other so that they can hopefully be aiming in the same direction, and if not at least recognise that there are differences in their goals or working standards.
Leg colour is important to araucana breeders, and only the white variety allows yellow legs. Cuckoo or barred and dark skin are difficult as the barring gene and the gene disallowing dark skin are closely related. However, it can be done--cuckoo silkies exist--some that have quite dark skin. It takes crossover to achieve this, and thus requires a lot of work over several generations.
Comb shape is easy--pea comb gene in dominant to single comb, so all F1 chicks should have pea combs, but also carry the single comb allele. If crossed back to parents or other araucanas, half of the F2s should be hom. for pea. With each generation the number of birds het. for pea comb will be reduced.
Rumpless and tufted will need to be selected for, but since tuftedness is quite variable in expression, and is dominant (indeed, a double dose is lethal) it shouldn't be any more difficult that breeding araucanas together. Same for rumplessnes, although it is not lethal--however it does have an impact on fertility; thus araucana breeders often use tailed birds.
