I took this to mean that matching from a *A card wasn't possible. If you have status with another alliance as well, then you could take the challenge. Might not help netd personally, of course!
I'm probably heading towards A3 - a bunch of US Air flights (the things we do for status!) followed by a BD business class sale to RAK will get me and Mrs NWIFlyer back to *G by the middle of March - reasonably comfortably ahead of the end-March deadline for BD's departure.
