I believe that my CMS lacks several features like SEO
It would be a lot easier to add the missing SEO.
Simply work out what you are missing and add it into your existing CMS. When you do have a closer look, you should realise that there is no "magic" and that all you need to do is automatically populate a few tags from the content record of the page.
The one thing that you may miss is page naming instead of using ID numbers, but that's no big deal as the novelty must by now have worn off that ploy.
