I do something like this already. I still go to the office on Monday and Tuesday, and Wednesday, but I'm tuned out. I'm in Do-Mode. On Thursday, its build and demo and test, so I snap out of it and put things together for a releasable build. Friday, fix bugs, do a new release for the test user to play with over the weekend. Now, none of this is firm - break the rule if needed. But, generally, this helps keep a fat chunk of attention all the way up front, weekend->Thursday, that makes the magic happen. Oddly enough, done right, it means Friday can be a slack day too.
