Yep. Did it this weekend. Moved main blog over to a different subdomain, added basic auth to stop it being crawled, added Simply Static, pressed button and a few minutes later the main site was updated.

Some perf tweaks I made were to point the main site’s wp-content/uploads at the WP htdocs via a nginx path mapping, and to tell SS to never export anything in uploads. Reduces the site generation to just the html, css, and JS.

The only issue I've found so far is that archive URLs like /YYYY/MM/, which would be handled by Wordpress to list all posts in that month, don't get exported by Simply Static. I suspect it's because they're all available by a select dropdown that's using a JS hook for onChange(). I solved this by creating an unlinked page, and put in an Archives block, then told Simply Static to add that unlinked page to the crawl list.

The other caution is that it doesn't export anything that's not linked. So if you've got no links to the yearly archives, then you get no index.html files for /YYYY/ either. Unfortunately, the Archives block in Wordpress doesn't offer a toggle between months and years, so you can't just create another block in the "archive finder" page and set it to years.

The support forum section of wordpress.org for the plugin appears to be a lot of people asking for support and no comments by the plugin author. If it works for you, then that's probably not an issue.
