There is no change to the img files.

I tryed scenario 3. and got the same problems. I think MapSource gets 
confused having two img's for the same area. Knowing this scenaro its 
required to have an option to turn it off.

Until now I created my maps as described in 4. But using a fix 
areas.list from splitter so I had not to rebuild contour lines osm again 
and again.

Actually I am working on the integrated contour line feature of mkgmap. 
It failed if a map didn't fit in a single DEM data file (SRTM, CGIAR or 
ASTER). For SRTM data I am now able to cover larger areas. The time went 
up from around 1.5 hours for my germany generation to 2 hours not 
counting the time previously required to generate and merge elevation 
osm with srtm2osm and osmosis. So this approach seems to be not slower 
and saves disk space.
