Does it matter how many files there are?
Anyhow it would be easily possible to use a subset of the files.

When I post the next patch of the precompiled sea the input files have 
osm of pbf format. Using osm format it is possible to correct floodings 
manually with JOSM.
So from my point of view the only reason to use the present coastline 
processing is that the precomiled sea uses not the very latest data and 
is compiled only from time to time.
Ok, maybe a second one: Precompiled sea uses the multipolygon algorithm. 
But it would be quite easy to add the polygon variant if required.
