Hi there
I'm not an SEO expert, but I think the best solution is to do it through .htaccess. You can keep the .html extension, and add a line to your .htaccess file that specifies that .html files should be executed as if they were .php. It won't affect any plain HTML files.
The line is as follows:
AddType application/x-httpd-php .htm .html
This isn't something you can do easily in CMSB, as far as I know. Sometimes the simplest solutions are the best ones?
