Then how about a godefroyae or a godefroyae-heavy cross? I suppose you could go with Gege Hughes or another copper complex as well and get flushes of pink.
I think a cross should be something new, so I wouldn't go with the godefroyae at all as greyii is mostly godefroyae. Perhaps a different Brachy like concolor? Or perhaps something really interesting like using Paph Hellas?
Hellas x delenatii gave us lovely flowers like Maisie Gay:
Who can guess how the callosum will influence the progeny from such a cross?
For a Brachy, I would try niveum as it tends to spread red into a nice pink blush in some circumstances. Or you could try back crossing it to delenatii in the hopes of improving the form. One other possibility is to use a good quality complex red. Orchids, Limited has a similar old cross made by Vacherot and Lecoufle, Paph Atlantinet = Atlantis x Madame Martinet, which they then used to make Paph Pink Atlantis. You could perhaps contact Jason or Robert (Drorchid) to see if they have a picture. Here's a picture of a Paph Pink Atlantis = Atlantinet x Blanche Sawyer that I bought from Orchids, Limited a few years ago.
