God knows why you would want to do any of that, but it would be clever. ;)
God may not know why *WMF* would want to do that... but, say it with me now:
WMF isn't the only client for Mediawiki.
By "you" I meant all users of Mediawiki. I can't see why anyone would want such a feature, it just appealed to me as cool from a technical perspective, so I thought I'd mention it.
