These are interesting ideas, Pearl, and probably fairly effective in somewhere like a rental where you're limited in what you can do to the house. Your new house design is also rather interesting, but fairly mechanically complex. With many moving parts, I fear the risk of failure is quite a bit higher.
I'm curious if you've come across Passive House concepts at all? What I'm getting at is that all these modifications are only necessary because the window itself performs poorly, so why not just get a better window? Your south facade in your design already looks great, with a lot of windows to capture that free heat from the sun in the cold season. Higher performing windows can let that heat in while still insulating the cold out while also not frosting up, reducing the moisture issues that that brings about. For the summer season, have your roof overhangs (or awnings) extend far enough to shade the windows, keeping the heat out while the inside remains cool. Suncalc.org can help you get the sun angle at different points in the year, you'll just have to do a bit of trigonometry to figure out the optimal overhang. Exterior shades can accomplish the same thing, but introduce more mechanical points that could fail. Interior shades can help slightly, but it's harder to get the heat back out once it's already made its way in.
An air tight install of a high performance window will eliminate drafts and keep the face of the window thermally comfortable, removing the need for complex insulation systems that obscure the light and view, which is the primary reason a window is there in the first place. I live in a place that is likely to see -40C in winter and +40C in summer, and it's incredible how properly installed high performance windows and corresponding shading can make both extremes still comfortable on the inside.
