By principle, they will probably not comp AC status for Pretige and for Elite (*Gold). If you are Super Elite with AC, and can demonstrate a "significant" amount of flying pattern, you might get Silver or Gold at most. It seems CX will NEVER comp anyone to Diamond.

You must note that the amount of miles you need to achieve Elite with AC (gold) is equal to amount you need for Silver (OW Ruby) with CX. So I would doubt they comp you to MPC Gold. If you are lucky, you might get silver.

If you email MPC, you will get a usual template response that they won't comp your status. You are better off talking to powerful travel agents who can give you a referral. If you also have many J or F class bookings with CX in the near future, that will help.

Bottom line is that if they DO comp you, they are doing you a big favor. Don't complain even if they don't act in your favor.
