For a while I did something similar. I used a private instance of WP to generate my blog content and then scraped the site to get static pages which I could then serve from another machine. That meant nothing dynamic, no WP "vuln of the week" treadmill, and no cache-layer validation headaches either. It worked pretty well. For a larger site I could have made the generation more selective, and (re)optimized the output in many different ways, but it wasn't worth it. Then I got off WP entirely and it was all a moot point, but it's an approach to consider for those stuck in WP-land.
