I personally don’t think that this is viable.
There are too many variables for decide a schedule to deliver updates. Sometimes a gamebreaking vulnerability appears, sometime the bugfix needs… more cooking time to be well done (pun intended).
The only thing I can suggest you is to wait at least two/three weeks before install any update, and to a manual install, not a scheduled one. You can download the file at release, but upload it manually only when you’re “done” about stability safety and issue-free release.
