The more convenient way to import pages is to insert them through a Wikia database, because at times, when importing pages from Wikipedia, the modules that's visible in Wikipedia will be missing in Wikia, and that's when 'script errors' start to appear.

But yes, it's possible to reverse the import. You can simply delete the imported pages.
