This idea has very little to do with categories. It has to do with structured data, and would be looking very strange to show up in the category page, as it is meant to just be a list of pages within a category. What you want has been done using Semantic MediaWiki, but it is done in such a hacky manner that it cannot be adapted to all wikis without serious performance problems.

The first problem is that there is no way for any algorithmn to detect to automatically detect which fields you want unless they are anotated in some way. The second is that those fields will be different in other wikis.

So maintenance is a given, although if your wiki uses Portable infoboxes then it is already possible to retrieve these fields using JavaScript, see dev wiki, it still won't fix the difficulty of maintenance.

The point is that you are better of implementing this the way you know, or requesting staff directly. Don't hold your breath though, as they've been making claims of bringing for structured data for years.
