Are streamed levels overkill for tiny objects?

I’m making a procedural level generator. It already fully works but I’m rewriting it so it uses prebuilt Levels that get streamed for each “room” instead of actors.

I’m wondering if I should stick to using Actors for some of the tinier objects, like doors, decorations, etc…

Or is it OK to have even tiny objects be levels? Even if it contains a single static mesh. It will greatly simplify my code if I don’t need to support both approaches.
