Sliding Window Option?

Skot,
I really like your idea. Maybe a project for me in the future as well.
The pictures show what I did on my doors and the McMaster Carr H channel I used. The channels I used are about 1/8 inch and the moving Lexan might be able to overlap the aft fixed section within the channel. I just checked and if the Lexan on the moving section was the .030 thickness, it will fit in the channel side by side with some adhesive backed felt on the edges of the moving section. This would keep it from rubbing against the fixed section and help prevent scratching. It would be a fun challenge. Back in the day, I was taking almost weekly photos of an 18 month construction project and back then, I had to open the door to get the quality I wanted. Your idea would eliminate the door closing challenge.

I don' t know where the pictures went, but will try again - Sorry.

Skot,
One more thought. If you decide to use the H channel, you will need to protect the channel from collapsing when bending it to match the curve of the door frame. I packed the channels on each side with thin strips of aluminum to slightly over tight. This prevented collapsing. For the really thin aluminum, I used roof flashing from Lowe's.
