Your question was answered in the first reply. The answer is no, & it still applies if you exclude iWork 09 & iLife 09 & their updates. This is not just because of DVD capacity limitations. It is also because the installer DVD runs a number of checks on its contents, which would fail if you replace any of its installer packages with newer ones, & because the various packages are associated with "preflight," "postflight," & other script processes that would have to be changed as well.
IOW, the installer DVD doesn't just install a preset list of files; it goes through a complex process of checking, assembling, linking, & configuring the OS as it installs it, including creating default preference & other files appropriate for the target Mac.
It would not be impossible to alter everything involved to include the updated changes, but it would require a careful study of the interdependencies of the packages & scripts, modifying them as needed, creating new checksums, & so on -- basically, re-authoring the whole DVD. With tens of thousands of individual files being installed, this would not be quick or easy to do, & given the frequency of update releases, the results would not be worth it.
As suggested, a much more practical approach is to clone a freshly installed & updated startup drive -- IOW, to copy the end result of the installation process.
As for reinstalling the OS to get rid of whatever degradation of its performance occurs over time, assuming the file system & hardware are healthy, all you might need to do is empty the caches from time to time. Some of them grow quite large & there is a small performance penalty associated with the need to sort through some of them to get the appropriate cached data. However, since cached data speed up day-to-day use, you should not do this very often, at most a few times a year, or the result will be a net loss of responsiveness as the caches are repeatedly recreated & filled with needed data.
Also keep in mind that the net performance gain from 'cleaned' caches is small, so if you are seeing significant degradation of performance over time, you probably have some specific problem that needs to be addressed directly, rather than by the "nuclear" solution of reinstalling the OS.
