Probably the only way that would happen is if the pilot groups got AA seniority numbers, and benefits OR the 3 WOs were combined into one...

This isn't the military, - lot of guys and girls are picking regionals based on location. A big part of the WO marketing strategy is stability during a regional career...Arbitrarily moving pilots around from one companies bases to another will stop people from applying to the WOs due to the added uncertainty.
