That would be interesting to see what would come from an araucana based bird and a Chinese blue egg breed. From the current research available the gene injected by the retrovirus actually activates the blue egg gene. Although both breeds essentially have the same activation code added to their DNA, the location of this code is different. This means that the South American and Asian blue egg chickens developed the ability to lay blue eggs independently.
This could mean that a hybrid would essentially have an enhanced blue egg ability... or because the code is just code that activates the already existing gene, it could be that there is no gain in blue colour.
You can get fibromelanosis, the blue egg gene, and a straight comb from crosses between Silverudd's Blue (AKA blue Isbar) and the Svart Hona. There is a breeder who sells them as "Swedish Blue Hens". I have also seen them called "Swedish Bluebars".
I think it makes an attractive mix, though sort of small. Should lay fairly well, and also have a pleasant temperament.
Know of any other breeders?
I got the picture above from the Facebook page of Cedar Crest farm and feed in Ohio. http://www.facebook.com/cedarcrestfarmohio/
They don't mention them on their main web page. I also noticed Graceful chickens no longer has their main web page, maybe they stopped raising chickens or something.
Hmm. Well, it would still be a simple enough cross to do yourself if you wanted. The single comb is always nice in my opinion, because it helps the birds cool off. From what I have seen, summer heat is more deadly to chickens than frostbitten combs.
I'm sure there are people crossing Cemanis with Legbars as well, to try and achieve something similar. I don't think that would be as successful though, because the barring gene (from the Legbar) supposedly messes up fibromelanism. Isbars are probably the better choice for obtaining the blue egg gene.
