If it's bantam sized, maybe columbian cochin bantams?
That's a great idea that I've thought about doing as well. I'm definitely going to make gamefowl mixes just because I love their friendliness towards people, broody abilities, foraging skills, and alertness. I probably won't try to make it...
Silkie feathering is recessive, so you'll either have to cross her back to her father, or to her siblings. Mottling (the white spots on mille fleur) are also recessive.
I'm not that into purebred chickens, since I like variety and non-standard colors. But, if I did create a variety, it would either be blue laced red sebrights or hen-feathered old English game bantams.
