Ddrescue can already accept such a mapfile. Just try the option '-L':

http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Invoking-ddrescue

-L
--loose-domain
    Accept an incomplete synthetic (user fabricated) domain mapfile or 
test-mode mapfile, and fill the gaps in the list of data blocks with 
non-tried blocks. The blocks in the mapfile must be strictly ascending and 
non-overlapping, but they don't need to be contiguous. This option allows 
making quick edits to a mapfile without all the size calculations involved 
in making all data blocks contiguous again.


Best regards,
Antonio.
