Jacen Solo was comfortable taking on anybody in the galaxy but Luke with one hand; he established firm dominance over Jaina this way in their final fight and had previously bested Katarn and three other Jedi at the same time. Meanwhile, Luke's a better combatant one on one than Jacen and far more powerful.
I'd say he takes it.

To be fair the only wanted to place a tracker on him, not kill him.
I say this trio is too powerful and familiar with Luke for him to take the win. Id give team 8/10. He would make them work very hard.
