Feather color genetics

Hi everyone!
Has anyone tried for wheat rumpless araucana rooster with black copper marans hens? I read what combinations can come from it, but has anyone tried it and can share some photos with me? Thank you in advance!
Attached a pic of my handsome rooster, Phoenix

Rumpless is dominant but he may only have one copy. You will get rumpless (and maybe some tailed) olive eggers with pea combs (more like an intermediate, a pingle comb like the father), single combs, and beards, and the same coloration as their mothers.

I thought rumpless was a lethal allele. So he should only have 1 copy period, right?
