The original request was for basically zero (planned) downtime. Your proposed solution would require "a few minutes" here and "a few minutes" there which quickly adds up so no instead of 100% uptime you're at 99.999% or less (which is still great, but not 100%). Then what happens if you "forgot" something and have to do it again? Testing the solution again introduces these "few minutes". It quickly adds up.
