Unlikely. Aside from complicating William and Mary's claims to the throne, if James doing a runner constitutes his abdication then why does he get to keep one of the states?, it gives James an independent power base close to England and Scotland and means they're going to have to constantly have one eye constantly over their shoulder in case he should ever try to ally with one of their continental opponents to invade. If William and Mary lose at the Boyne to fully secure their rule then they're simply going to keep coming back as many times as necessary until they win.
