Now that my kids are grown I would absolutely love this. You can stay in the pocket, get a quieter few days over the working weekend and it would help enforce good comms/docs when you wrap up your week.
The only issue is that I would try to pack too much into the 5 day 'weekend' and be exhausted when I start back up.
Could be. My step-dad was just telling me about his night shift at AT&T in the 70's doing operations for switching sytems. They would to 10 8's in a row b/c it was hard for them to stay on the night shift schedule over the weekends, so this just let them stretch the weekend. He really liked it.
