Once they are imported ... if they were all in one forum ... you could use XenPorta to display them all.
It would be like http://8wayrun.com/
The most recent articles would be on the home page and the remaining articles would be on successive pages.
You might be able to use native Xenforo Prefixes to group the articles ... it would be one prefix per article. Then use the Prefix listing addon (forget who made it) to display all the prefixes.
