In theory this will probably work. However, Google is pretty savvy and may catch on. Google regularly crawl these sites and noticed that these links are 404's. All of sudden, these links point to a live domain w/a 301 to a new site. If this a common occurrence, the pattern may be recognized and they take some sort of action. Good luck!

Yeah, with above. There is absolutely no difference if your making your website in PHP, HTML 4 or 5, it all comes down (the output) to the very same, HTML! A CMS is just a way to 'manage' the content on your website in a dynamic way, without FTP'ing your way around with files. With dynamic it's simply being extracted from often a SQL related database or so.
