Data Deduplication with the help of an online filesystem check

Hello,
I would like to know if it would be possible to implement the following
feature in btrfs:

Have an online filesystem check which accounts for possible duplicated
data blocks (maybe with the help of already implemented checksums: Are
these checksums for the whole file or block based?) and de duplicate
these blocks?
