Eliminating inner skylight from shower

Yesterday I finally got around to replacing the old cracked and matched outer skylight over my shower. Took most of the day but I'm confident it was successful. (Used butyl tape underneath and Eternabond on top.) I loved all the light that gets in! When I put the inner skylight back in I was struck by how much this reduced the light. I thought, why do I need the inner skylight anyway?

I could dress up the rough opening between the two skylights with white shower paneling, caulk the corners, add some trim pieces, and have a clean neat hole extending from the ceiling up to the roof skylight. And let lots more light in.

Anyone done this? Anyone want to talk me out of it? (Or encourage me?)

    And prepare yourself for the cold droplets of condensation dripping on you while showering.

    The air that is trapped between the inner and outer skylights provides a level of insulation that minimizes heat and cold in the bathroom. On a cold day, you will develop a lot of moisture on the outer cover if you don't have the inner cover when you take a shower. Since the outer cover is curved, this moisture can run down to the inner roof material. If you take off the inner cover, make sure you properly waterproof the area to preclude condensation from penetrating the roof material.
