Champagne Pastel
Champagne Cinnamon
Champagne Pewter
Champagne Pinstripe
and Puma Pied (not proven, but probably the same thing as a Champagne)
Kevin at NERD produced a few crosses too, but hasn't revealed what they are (I think one was a Champagne Hidden Gene Woma).

There may be more, but those are the ones I can think of
