If you guys want to try and see if it's doable on an automated level in BB/RB ("all I am saying is bare notes from Realtracks") just download Riffstation PC or Mac Trial and try the RiffBuilder on some of your realtracks, it pics up most of the RT tempos, obviously it's not going to give perfectly what you want that's what session musicians are for.
You can just drag a track out of BB\RB into RiffStation and you have the notation RealChart, just look at the time in the bottom of RiffStaion RiffBuilder to the time in the notation window in BB/RB of the RealChart to find notes.
If you have a problem with RiffStaion tempo just save a stereo render with the RT panned to the left and a click track (write Metronome to Track) panned to the right then RiffStaion will pick up the tempo.

Just spend a bit of time trying and playing around, who knows you might be the one who comes up with a whole knew idea on how to do things better, you might have that Eureka moment.
