I think it has not been thought out fully. As suggested, open a HH account for your wife and transfer the orphan miles to it. Also as suggested, open it before the end of June and claim online registration bonus and 2000 profile bonus. In July, update profile and claim another 2000 HH points. now she has 5000 and 7000 HH points. But, why bother with a household account. She can get 2000 each quarter for updating her account, at least 2000 HH points though automallonline.com and a few thousand through erewards.com. By this time next year she will have about 30000 HH points with it still growing!!!

If hilton comes out with more nonstay HH points, she could get them too!
