Is it bad to use Blueprints as more advanced grouping of meshes?

I was just wondering if using world geometry and turning some parts like complex walls and floors into blueprints so I can group them without using the other group tool that moves the origin making it difficult to snap to grids. Is it bad? would it effect rendering or lighting/like baking badly? I know I can at least have more customization options this way. I doubt there is prob an easy answer to this question but I thought I might get some better input from the community on this question.

Thanks

If you are using a lot of them then yes. It may affect the performance of the game because blueprints probably take more space in memory than just a simple mesh, blueprints also have tick events that will start to add up each frame. You could deactivate the ticking but I mean, they are not supposed to be used like that in the end. Nevertheless if you just have a few of them and they are not causing any trouble then you might as well do it your way.
