Since a user has to be logged into the forum to see others' profiles and trust page, will that user's name and avatar be displayed at the top of the archived page?  That's the only issue I would have with archives allowing pages to appear as they do for me when I'm logged in.  Maybe your archiving tool can incorporate Suchmoon's stealth code.

As for whether it's allowed or not, I really don't know.  I noticed other forums of which I'm a member don't display trade ratings in "guest" mode.  There might be some privacy concerns for those who've left the feedback as well.
