I would start with the four being discovered as force sensitive, during the mandalorian wars, similar to The Phantom Menace. Maybe they're on a planet being invaded by the mandalorians, while Shere Khan and a group of rebellious jedi fight back. After the battle is over they would be taken back to Coruscant to begin training.

I think so.
