I might be able to help (or confuse) :)

By taking the converted gov'nt data shape files (as a ready OSM file)
and slice it into 16 squares, then compare each square to the existing
OSM data square, and only those squares that have no 'natural=water &
similar tags' you would import the data. Then square it off again and
import the 'no OSM Data areas'.
So then your left with only a few small squares that need to be traced.

Does this make sence?
