What you're asking about there could amount to a fair amount of work and it probably too much to fully answer in a comment reply so an alternative... If you wanted to just do something quickly and then in slower time make the finer adjustments you could simply spider and download your current site with wget and then drop the resulting static html into Netlify. It's free and I just did that with an old Wordpress site that I didn't want to take the time to upgrade and deal with but needed to make secure right away. I kept a copy of the Wordpress install to work with locally and the live site now just returns static html hosted on Netlify that can't be attacked.
