I'm not sure this would be in AA's best interests even if UAL was willing to sell:
AA already flies nearly every NRT route UA serves and could fly to other Japanese cities if it wanted under the bilateral. The only restricted access parts of UA's current Pacific route structure is HKG and China although that is changing and the beyond NRT rights.
2. NRT is one of the most costly places to connect passengers through. I'm not sure that an airline today would want to build a route system that involves carrying connecting passengers through NRT. TPE is a much less costly airport for the SE Asian markets that require a stop somewhere in Asia.
