Does window tint work?
If you don't want new windows, sun-blocking window film or window tint is a good alternative. Compared to low-E windows, the overall cost of installing tinted film on clear glass is less expensive and newer version of window film can also help your home retain heat in the winter.

What I'm envisioning, I think, is basically a structural arch that the window is incidental filler for. Might be worth your time to look up arch construction, and see if there's anything useful to you in there. I'm envisioning the cathedrals where they build the arches, then rubble, artwork, or window fill the space under it, the ARCH being the structure, not the fill.

When the window frosted up, you opened the inner window, opened the batten, and closed the inner window. The ventilation would defrost the window.
You could do something similar for your window.
Houses move. In designing your window frame, you want to to allow some room for movement. Read a book on making your own doors and windows.
