I think the best examples of royales in ___ vs ___ series are Steve vs Emmet of VG vs History and Barney Stinson vs Johnny Bravo of Cartoons vs History, where it does flip flop back and forth between the two sides but it doesn't exactly have an even number of each side since royales typically are 5-way battles.
