I don't use Picard for tagging purposes but I believe that the 
MusicBrainz track ID is stored in the tags if you use Picard to tag your 
files. This means that the tracks you have are matched to the 
corresponding track in MusicBrainz. If you lookup your tracks again you 
will get an indication how much the tags match and you can choose to 
re-tag your files again if changed have been made to that track in the 
MB db.

So what you're looking for is already possible.
