Modular Saloon Interior

I’m not sure if this is the right place to ask, but I’m trying to make a tavern using the Modular Saloon Interior that’s available on Quixel Bridge. I’m having problems figuring out what to do with windows, because I can’t seem to find a lower wall that I could place under the window. I’ll attach the photo of what I’m trying to recreate.

Am I supposed to cut out the parts of the wall so the sun can shine through the window? Or do I need to use Maya/Blender to alter the models? The only wall assets I can find combine both the wallpaper and the lower wooden part of the wall.

I’m not familiar with that modular package. Silly question: Is there a full height wall module that you could stick into the floor under the windows?

Doesn’t seem like it, I don’t think I could make it right no matter how I do it, so I made it like this.
