I can't see any easy way to find AA codeshare flights going through the OneWorld Timetables offline program.
For non ex-USA based RTW... maximizing via North America, DFW-ANC appears to be just over the 3000 mile mark. So throwing in a roundtrip DFW-ANC-DFW while in North American would seem to bag an ExPlat an extra 24K miles.
