If you are still monitoring the list, I probably would try to merge xml dumps (only --current should be enough for search), then I'd import merged dump into "common" wiki. Should not be too hard, if not performance issues for very large wikis. If your wikis aren't very large, that is possible. However, that is offline slow process and adding of new pages has to be performed with slow re-merge. One may use remote api calls at individual wikis to duplicate-write every saved "individual" article into the "common" wiki, however an extension has do be developed for that. This way is much faster and keeps in sync. Dmitriy
There's also the transwiki feature.
