Hi anon,
Let's go with either KF or Asia Miles to simply this, and that you'll want to fly direct instead of say, backtracking through Hong Kong via Cathay because you want to try our their 'The Pier' lounge....
For KF, round trip x 2 in J would be 184K per person (regardless of SQ or *A awards) so you'll need 368K miles in general.
For Asia Miles, 140K if you want to fly return on BA, so 280K miles in total.
To simplify the analysis I am going to assume you are not particularly picky about the cabin type as long as it is business.
Based on 280K miles, if you exclusively earn it on 4mpd cards, that's $70K of spending. Considering that a revenue flight on BA to LHR is $6K round trip, that's getting $12K out of $70K of spending, or almost 20%. (but we know that's not really the case since you would never have spend $12K on the ticket anyway)
A more realistic expectation is that you mix 4mpd cards with your regular spend and earn a blended 2mpd on average. That raises the spend requirement to $140K. You're now getting around 8.5%, which is still pretty respectable.
Hope that gives you an idea.
