If only the title is visible (but the content is not), interesting problems arise:
You can perform "Show any pages that link to X" (Assuming X is visible). The result is a list of pageIDs, which can be resolved to titles.
This means that anyone can find all the links, templates, and images on a page whose content is not available.
Ultimately, it's this sort of subtle thing, that isn't obvious right off the bat, that means it's probably a very silly idea to try and modify MediaWiki to support this kind of complex read permissions. You'd be far better off rewriting the whole application from scratch, and there's no need to do that in light of other packages available.
