When I asked a couple of years ago, CX would not allow me to retroactively credit previous flight miles toward MPC club miles. I don't know if other people had a better luck.

AA PLT challenge would be the easier way than MPC to obtain OW status. However, keep in mind that only higher CX econ fares (Y/B/H) are eligible to earn AA miles/points. If you are going to be flying a lot on CX metal on discounted fares, you will probably earn more Asiamiles than you would AAvantage miles. If you fly premium, you will earn more AAdvantage miles with the 100% PLT bonus in addition to COS bonus.
