Moving through falling objects (loop)?

Hello, basically i would like to create a seamless loop where objects are falling on a floor while camera is flying through it.

I thought i can make a simple passive rigid body floor and have active objects falling on it. Have it all on collection and then instance that multiple times and offset the timings on the instances. But i don’t see a way i could offset the animation start timings on the instances?

How would you guys do it in the most simple way? Thank you!
