I think LinkPreview is what you're looking for. If you install that script on your wikia, then hovering over an internal link will provide a preview of that page.

To install the script, add this: dev:LinkPreview/code.js

to  on your wikia.

It's slightly different to Wikipedia's own version of link previews, but it's just as efficient.
