I'm wondering if it would be the best option to have a small tool, a binary 
exe wich does that, and offer the option in the colors KCM if the tool is 
installed (and likewise, perhaps offer the option to adjust color scheme to 
the wallpaper from the wallpaper dialog in that case (if we deem that useful), 
and in plasma-sdk somehow?

Putting it into a library to have the code shared sounds a bit meh since it's 
super specific, the API would have to be stable, and I'm not sure if it's 
actually all that useful having a compile time dependency compared to a 
runtime dep.
