The problem with this is that, in the case of IRROPS or possible OPUPs, he will show as an AA paper rather that a CX Sapphire and would/should be treated accordingly.
OW carriers using Amadeus have two fields for FF numbers, one for mileage accrual, one for benefitts. You'll need to have the AA number (well, alpha-numeric) in the mileage accrual field, and the CX number in the benefits field.
If done properly, this will send the points to AA while telling thee operating carrier that you are a OW Sapphire.
I can't remember the commands off the top of my head, but I am sure
number_6 will be along shortly to advise on this.
