I want to caution that it is still better to update on Tuesday morning in case the update fails. Updating before or on the weekend can lead to your releases spiraling out of control with no staff monitoring or just a skeleton crew.
It is better to have your whole team available and awake. I also worry that you might forment resentment by making everyone work every release weekend. Releases will likely become more infrequent, and lead to bigger changes and bigger failures.
Please consider that Balsamiq did recover. May be harder to do so on Saturday.
