We are in the process of buying a home and looking for some ideas for an interior wall on the upper level which is made of shutters and windows overlooking into the main level. I have attached a couple of pictures.

The current owner probably did that to get maximum light in that upper bedroom.

I'm looking for ideas for how to change the look of that wall. Thinking of following options.

1. Remove all the frames of those windows and add a drywall. This option will definitely limit the amount of light that bedroom currently gets. Not sure how much this option will cost.
2. Another option is to keep those frames and replace the shutter windows with frosted glass panels using the existing frame and add color to the trim to match the color on the hand rails of stairs. This option can get enough light into that room.

I'm looking forward for more ideas.
