Not likely, unless the APA comes up with more concessions in compensation to pay for that demand. They'd be the ONLY Major airline pilot group flying their RJ feed system too and that would be unprecedented and (for AMR) unthinkable.

I think it's pretty clear that AMR believes it cannot afford to bend over and has no plans to. The APA cannot afford to blink (lest their leadership be drawn and quartered by the membership), so that means the most likely scenario is a nasty confrontation that the courts will ultimately solve.

Look for a much smaller AA and substantially relaxed scope. AMR ultimately believes it will be more profitable and competitive with that equation anyway and although many pilots might quit, they'll be hideously overstaffed anyway if there plan comes to fruition.

Barring a sudden and unlikely embracement of compromise by the APA, this conflagration is inevitable and IMO, AMR will come out far less bloody then the pilots.
