You can certainly edit the html file and send it to an editor to re-upload. To migrate it to a member submission would be nicer, but harder; if we created a member submission page and could attach the current itemID I think it would correctly assign favorites, comments, etc., but I'm not sure if lacking the MS prefix of a member submission would break anything? There are surely also absolute links to this page, so we'd need a redirect, but that's no problem.
