What you are trying to do would normally be done in a composite, but you might be able to accomplish this with a cleverly constrained boolean material/object, such that the hole is always pointing directly at the camera and perfectly fits the bounds of the inner object, revealing just the part of the interior you want visible. It really depends on how complex the geometry of the inner object is. I'm assuming spheres and cubes are just simple examples.
You might explore the AOV system along with render layers to accomplish this, essentially executing a multi-render composite but doing it all in one go. It seems like the sort of thing that might be able to handle, but I honestly haven't had the time to understand the Ever Expanding Power of AOVs over the last few releases. I may also be thinking of stuff that's happening with the Octane 2024 Alphas.
