Again these hennies aren't mine. Just examples of there colouring they throw. Even the lre tails can come in white also. Closest I found to what you aimed to create, enough splashing in the tail, with traditional brown hen coloring. May be easier to produce, reproduce. Your just leaning towards the splash tails side of the lines, same as spotting a future hen to breed to.
The more line bred the hen, the more line bred the cock. The less variations you ŵill get . Still needing to refresh roosters of the same lines.
