Hmmm, if Suguha didn't meet until the boss-battle, then Asuna and Kirito would have still met under similar circumstances, and their love may have still came to be. That's just a theory though.

Really, when you ask, "What if Leafa was in SAO" the outcome is mostly determined by a few questions. "Did Kirito and Suguha know that the other was in the game, before entering?" is probably one of the questions that would make the biggest difference in how everything plays out. Just my thoughts...
