Good luck , but you should be aware ( and your travel agent should have warned you) that CX are quite vigilant about illegally booked flights - if they pick these flights up they have the right to cancel them ( or indeed AA could if they notice them in their res system without the requisite connecting flights ) . Please note that I am not saying this will happen - but it can - as a former Travel Agent I have seen this before and it can get quite ugly as you will not necessarily be able to rebook the flights onto the CX flight number if they are running full - this can result in you being stranded en route ( and usually they scrutinise full flights more carefully so the odds are if these segments get cancelled it will be because it is a packed flight . ) A colleague of mine had a pax stranded in Asia last year ( can't recall which city it got picked up in ) for this very reason - it cost him a great deal of time /money and stress to sort it out


I hope that you don't have any problems - but it is important that you are aware of the possible consequences if you do get caught .
