Hm, Really, it might be possible to use Track Archives to do this. You will still need to route your sends, but inserts should carry over. P. 696 in the manual.
The possible show stoppers are that Folder Tracks and VST Rack instruments can't be exported (VST Instrument Tracks) can though.)
Tempo track is exported separately, contains tempo and time sigs, you can only have one.
You would end up with some work to do, but depending on what's in those projects it could work.
