Hi!

I don't see any difference between merging externally generated contour lines into one IMG file or generating the contour lines with mkgmap - the resulting IMG file looks the same.
The difference is what is being published: You may not create a map from both sources and redistribute it. But you may distribute each layer seperately and let the end user combine them into a map, which he may not redistribute.
And I don't agree that this would be a derived work. OSM does not contain any DEM data or contour lines, so by adding them the OSM layer remains unchanged and clearly discernible from the contour lines, so I would say the result is a collective work.
Discernible is not enough. You need to read through the full legalese. A collective work is defined as a collection of unmodified entities. This is definitely not true for a gmapsupp.img.
Took me a while to understand and believe how bad the current OSM licence is, too.
