The only Lifetime Emerald status I can think of is Cathay Pacific's Marco Polo Club - Invitational Diamond Level.

One may be invited to this level only on the basis of proven flight records (preferbly on CX), hold an executive decision-making position that would affect thousands of potential CX customers under its command, or is a VIP holding super-star status known not only in HK but worldwide as well.

You may try contacting CX in London about this.. but the chances are, if you're not already a Diamond member with the Marco Polo Club, you have to prove to them why they should give you something for nothing. As it is, CX's Diamond level is the hardest to obtain when compared to all of the other OW FF programmes. Like BA, you gain status in tiers. ie 0->30,000 miles gets you Silver (OW Ruby), then the tier points zero down, (but your award points remain active). You would then need another 60K to gain Gold level, and then from there another 120K to gain Diamond. You may accrue your mileage on either Asiamiles or BAmiles (for UK residents only) but the latter is only miles and not status.

So here's something to work towards.
