Thanks for your suggestion, but among other things that sheet of plastic
would get all frosted in the winter (it gets down to 0° F here), and the
heat loss through the pane (roughly 27 X 27") would be quite large. Finally,
the window has an aluminum frame and to remove either window is a big pain.

Replace glass with a sheet of "Lexan" or "Perspex". Then you can drill
all the holes you like. If you move out, put the glass back in.
