Baking multiple objects in same position

Hi all
I have a question regarding baking, so i'm developing a game that has a map and in that map there are buildings each building can be upgraded to the next level but since those buildings are static i want to bake the light for each level, my question is do you guys have a suggestion how to bake the light on 12 duplicated buildings (12 different levels) that are having the same position on the plane?

Will baking all the 12 buildings in another scene and just load scene additive and position them in the correct coordinates and disable objects based on current levels will work?

 

I haven’t tied this, but it may work.

Use LOD group component to bake all of the buildings in the same place.

you can then disable the component and enable only the building that you want at any given time.
