show the biggest offending directories

[duplisea]

My most common important duplication error is having directories fully copied but with different names. So fdupes finds all the files that are duplicated but it is verbose output since it may be that the whole directory is duplicated which is sufficient information. In this case, it is just easiest and best to go in and delete one of those directories by myself. So is it possible to list say the top three offending directory duplications by size and not just number of files with a flag option?
