Hi Phil,
Possibly no need to rewrite core for your needs. There is a Generico filter template/bundle named, Course Information for Tutors and administrators, that provides much of what you are asking for, and you could easily modify it, or even use other template/bundles for other items. Add it to the course description to show the course info. Right out of the box, it needs to be modified as there are links in the template that will have to be changed to point to your Moodle site. It is discusse in https://moodle.org/mod/forum/discuss.php?d=324771#p1584860. Note: I do not use this, but it looks interesting.
The really nice thing about adding the Generico filter plugin to your site, is there are already so many other template/bundles available that come with the plugin, that really let you do some amazing things on your site. Typically, any place in Moodle that you can open an editor, can have a Generico filter added. The forum link listed, has links to many more template/bundles.
