You cannot expect even remotely similar functionality from such imported pages. See http://wikiworks.com/enterprise-mediawiki-vs-sharepoint.html for an explanation of why you might want to reconsider this type of migration. You will lose 1. reliable endless version control and archiving. 2. Simple editing of several authors. 3. all the features of the mediawiki extensions, at the end of 2000.
In some companies, for example. insurance, law firms or accounting, loss 1. may have legal consequences.
If your intention is to simply make the pages visible in SharePoint, which are supported in MediaWiki, then you can do this by setting SharePoint to search in the media - by looking at some other issues here on StackExchange.
