Some wikis do this already, but many others link to Wikiapedia about the topic instead of the associated wiki. You can become closer to achieving cross-wiki integration by asking Admins on the wikis in question if adding such links would be okay. Affiliated wikis commonly link to each other's articles and some fanon link to the canon counterpart. Plus there has been a push by WikiIndex, a wiki about all wikis, for wikis to create WikiNodes that look similar to this. The goal is to create a mass network, like a spider web, where editors can easily bounce from wiki to wiki through related wikis' WikiNodes. Though many Wikia wikis do not have WikiNodes created on their wiki to bounce between.

As for a "program," what would you have in mind? I think perhaps promoting cross-wiki links would be a better idea than a groups of people going around to wikis and linking them together.
