Lavender barred rocks???

[Chiry chickens]

I would like to end up with lavender with barring that will breed true. I have tried to research this but I can't find anything. In theory it should work. But if it was that easy I feel like someone would have tried it, lavender and blue seem to be popular these days. I have seen some barred BO that I bealieve were a buff / cuckoo cross I'm looking for something similar but distinctive barring in lavender / blue. Maybe I'm asking for to much....

At Chirpy Chickens western Australia we have a little flock of lavender barred rock that we are continuing to improve to getting standard.
