If the UK standard (adapted to an American format) is pursued I think the basic genetics for attaining that standard already exist in the US. I quote from a UK friend who has seen pictures of our birds and who has raised and shown some of the best cream legbars in the UK:
I went through alot of birds with gold neck hackles to start with! I finally managed to source some with cream/grey neck hackles and a boy who had hardly any colour and went from there really. In the first year I bred the light coloured male with hens who had more grey than cream in their neck hackles as this mating produced good pullets with pretty much 50/50 cream/grey necks and went on from there. Your birds look pretty nice to me, if I had to find any fault I would say that the males chest looks slightly dark and the female's barring is quite distinctive, it should be a bit softer. The male has a great straight comb though! They are the right colour so you have a good base to work from.
So, with the focused effort of the group here and others who will come later I don't foresee any insurmountable barriers to achieving the UK standard with the steady application of effort over time.
