You had a faster way to level up in the game, just have the Manual Magic Pot summon, fight a level 100 Average Tactician EX-Death, let him break you, summon MP and then bam, easy kill and hundreds of thousands of EXP :D. If you fill your accesory slots with Chocobo accesories, and it's your bonus day, you'll get 2 million EXP, instant level up to 100.
Two heroes and two antagonists would be the best option actually, I would love to play with Rinoa, Rydia, Yuna, Tifa/Aeris, Locke, Edea, Jenova, Gestalth, Gilgamesh, Zeromus....the list goes on xD
