This is really cool Lorenzo!

I’d like to suggest you take a look at the indieweb movement.

There are new technologies, like webmentions that you could use to implement likes and reply in a federated way.

And a static site like yours (or mine), can leverage https://webmention.io/ as a free backend.

As an example, this reply was posted on my own site, and syndicated here on your Disqus.
