Simple...
Blue golden duckwing American Game. Those are literally red white and blue and I think the name is quite American. (I think barring wouldn't be too hard to incorporate.)
In the fantasy realm of my mind in a world of bottomless forever-clean bedding and perfect weather strut large, fluffy birds similar to Faverolles but with long, graceful legs with beards that are long enough to drag on the ground.
I would never ever ever own one because maintenance and it is...
I suppose that something with a rose comb and feathered legs has never been developed before, but I have a strong impression that it would be a hideous abomination...
I know these already exist, but for the purpose of expanding the gene pool the initial cross would be Rosecomb bantams with Anconas, creating rosecombed bantam Anconas! Now, some work would be involved, but it's entirely doable.
