The functionality would be much the same as Special:PrefixIndex, only listing your wikilinks in the lower part of the page. With an optional Namespace:Pagename passed as parametersm the drop downs would be prefilled.

You select the wiki you wish to see the parametered page on and it will take you to it, or its CreatePage editor.

By its very nature, the listing of *your* wikilinks populating this "Special:YourWiki" (ListWikis?) page would be only those belonging to the User which is invoking it.
