HELP: Different Lighting & Scene Set ups for one Turn Table Animation for Testing in Sequencer

Ok so here’s what I’m working on:

I have a character set up with different cameras in a turn table animation.

I have a separate Level Sequence for each camera to make it easy to go back and render each one without confusion.

What I want to do is without changing any of the above set it up to have different types of background lighting, HDRI, Props and scenes.

This is all just for testing.

What I need help with is how exactly do I set up these different variations in background and lighting elements in Sequencer?

I’m trying to make this as simple as possible so that anyone can come in and choose the set they want to quickly render it out in Movie Render Que.
