Generate Content Based on RSS Feed

I was wondering if it would be possible to generate a page based on an RSS feed.

I have a rough idea on how this would be implemented if I have to write this from the ground up but I was wondering if anyone has already done so?

Basically I’d like to point to an RSS feed and when someone goes to a custom create page called /topic/

It would pull all the posts from foobar.site/rss/ and generate a listing of all the current posts on that site.

We wouldn’t need to have a page on the site to read the post, just essentially the post index page bonus point for pagination.

Any thoughts on existing solutions?

Right now what I have in mind is a custom page and do a javascript code injection that would set a global variable for the RSS feed value.
