I would breed her to both the proven Lesser male and your Orange Ghost male. Since both your male OG and your female OG are homozygous, ALL hatchlings from this pairing will be OGs. Hatchlings from the Lesser would be either Lesser Het OG or Normal Het OG. That way if you plan on selling them, you can sell them in groups like 1.0 Lesser Het OG and 0.2 OGs.

The other pairing that I'd consider is going the double recessive route. Breed her to both your Orange Ghost male and your Pied male. Once again, all hatchlings from the OG male will be homozygous OG. All hatchlings from the Pied male will be Normal, Double Het for Orange Ghost Pied. Because of the homozygous x homozygous pairing, all normal appearing hatchlings are Double Het OG/Pied while all Orange Ghosts are just regular Orange Ghosts.
