Cuckoo x buff?

I've got a Cuckoo Orpington x Light Sussex rooster and I was wondering if I cross him with Buff Orpington what the chicks would come out as?

I’m not an expert, but I think that the black would stay, and the white might be replaced by the buff color.

Thanks! That would be interesting if it did come out like that.
It will be a while till I can try it as the BO are still pullets.
