It is not advisable as even if you save all the updates they need to be installed in a particular order and that is not published by MS as far as I know. Also any hardware changes could require different updates.
I agree with alanrwood. Quite apart from anything else, MS do tend to learn from errors, so may well update updates (if you see what I mean) and others are overtaken by events. It does take some time to complete the updates process, and quite a few reboots as well, but IMHO the effort is well worth it.
