This is possible with level streaming, we've been using this to have multiple variations of multiple levels for a project.

The only caveat is that level streaming has some latency so you have to make sure that you set up the blueprints correctly, this stops you from using while and for loops for example.

Thank you, brother. 

Hi,

We've noticed that there have been questions and confusion regarding the various level-switching methods available in Unreal, and how these can be effectively utilized with Aximmetry. To address this, we have created a comprehensive document detailing the process of level (or scene map) switching within Unreal Engine.
You can read the document here: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/obtaining-graphics-and-virtual-assets/creating-content-for-aximmetry-de/advanced-information-and-features/switching-scenes-with-levels  

Warmest regards,
