There's no award to let you do that. There are oneWorld awards which allow you to use multiple carriers, but it costs lots more miles and restricts you to oneWorld [which doesn't include JAL].</font>
Well - there is no AA award that would let you do that. But, for example, if you had miles in a BA scheme (the European one at least - not sure about US) the one-way award miles is 50% of the two-way, and both CX and JAL are eligible for award flights. So it looks like what you want to do might be possible that way.
