olive eggers

I'm new to genetics, can anyone tell me if you can get autosexing chicks from Silver Crested Cream Legbars and Cuckoo Marans? I know if you put a black rooster with the Cuckoo's, they'll be autosexing, and Cream Legbars are autosexing by themselves, or you can put Bielefelders and CLs together...

So I've been doing a lot of reading up and I really want to make an olive egger next year, but I want it to be autosexing. I've read up on the genetics and how to make it and saw something like this: cream Legbar cockerel + cuckoo Marans F1 barred cockerel + cuckoo Marans F2 barred cockerel...
