If you like the little hen I would get her. There's nothing prettier than blue and buff together. We have some Orpington chicks at the moment from a breeder that keeps mixed pens. We have one that is so pretty, very soft, clear gold on her front half and very pretty lacing on her wings and back...
There are people who have tried that mix on here and you get black laced buff/brown or sometimes grey birds. Just do a search and it should pop up. To get blue and buff on a bird the rooster needs to be a splash and the hen a buff.
