Thats going to be a pain, think of all of the information that would have to be moved, the site would be down for weeks just re arranging everything. i see how it may be a pain if your looking for something specific, but everyone usually has the year/make/model listed in the title so you can skim through the threads a little quicker. if there is a quick fix or easy way to do it, that would be cool, but i don't see it not being an issue.
