First I think a hypothetical congratulations would be in order!
But as for how to treat such a bulb on receiving... I think Rick has good advice. When I sent asiatics north I gave them a spell in the fridge before they left but they still had a tough time adjusting. I think I gave them 10-12 weeks but in retrospect I don't think it was long enough.
Is it at all possible to try scaling the bulb? After the warm incubation any bulblets could go through a cold period that might take them through into synch. with your next spring. I have no idea about scaling North Americans though. It might be a terrible idea!
