It seems that the photos did not make it through. Maybe try again?
It's really hard to sunburn indoor succulents, at least if they aren't coming out of deep shade. I wouldn't be at all concerned about that if you are rotating plants through the brightest area.
I'm curious to hear how your strategy works out. I think this idea of rotating plants through the sunny windowsill has some potential.
The best rotation would be the most even one, over time. I would think shorter intervals would make more sense, like weekly, or whatever you can tolerate dealing with.
There is not a huge difference between better and worse indirect sunlight, to the extent that both fall short. There's a decent number of succulents that don't need to see the sun every day, like the holiday cacti for example, but most succulents are kind of picky about this.
One thing you might want to consider as we head into late fall and winter... plants that aren't in the sun will tend to need less water, especially given short days and lower temps. So if you decide to separate some plants to live permanently in a darker area, they may need water half as often as the others, or something like that.
