I believe such a feature already exists on some wikis, where you can 'borrow' a wiki's image and video database for use on another wiki. Essentially, wiki-1 uploads an image and it appears on both wiki-1 and wiki-2, but this doesn't work vice-versa. However, I'm not sure if that's because it'll cause some kind of infinite loop or because it's just not been done in the single case I've seen it.

It apparently works on w:c:vi.avatar who use w:c:avatar as a database of videos and images as well as having their own. Something like enabling SahredCommons I guess. To enable it, you'll need to send in a request to staff via Special:Contact/general and ask the wiki whose images/videos you'd like to use (asking an admin on their message wall/talk page will suffice).

As for sharing pages for translation material, I don't think that works in quite the same way. I think there are ways of doing it, but it's likely translating the page name then looking it up on the other language wiki to see if it exists. Google translate might be a good way of looking for this sort of thing.
