I'd like to get myself some *A status.

I am a flexible traveller, actively scanning the premium fare deals forum for business class fares on OW and *A. Going to reach CX Gold / OW Sapphire this year and it looks like I will manage to get some *A status as well.
I have already accumulated some business class flights on ANA and some Eco flights on SQ with blank bp, ready to retro-claim, see below:

I'm considering to retro-claim them to TK Miles & Smiles, already have an account without any activity there.
I have one family member with the exact same flights, so if the program allows combining miles to make redemption bookings, I guess it would be an advantage.
I don't know if any other programs allow this and my question is if TK would be the best program to retro-claim the past flights?

Apart from TK I also have existing accounts with LH, SQ, TG and United, only LH has some miles in it, but no status miles.
Should I sign up for any other program as well for future flights?
