If Gear 5 can revive others through Nika, then yeah he would laugh way harder than he usually does
Edit: It would also be pretty funny and I would like it, it would show why Joy Boy and Nika are such a big deal and the light completely overcoming the darkness
Edit: Imagine if Dragon fights against Imu and dies then Luffy jumps to where they are fighting, revives him, and they both start to fight against Imu, it would just show darkness being completely overwhelmed by the light,
