If you go on ba.com then you will see that is how much J tickets cost, even the cheapest direct return J to Japan on BA would be £5k, doubt it you will find for £4k. So it is the same as on current system, two times long haul J give you silver.

I now fly AY to Japan via HEL as BA is to expensive for me, but even that is at least about £3.7k.

We are talking only £7.5k to reach silver, that is a rather trivial amount of money, even for personal traveler. And I am not some wealthy dude.
