osgEarth has shaders that it can run on the terrain in realtime that could perform this modification. You could probably also dynamically add and remove inset layers that would override the existing elevation without even writing a shader.
Contact me privately if you want some more info about either of these approaches. Generally I prefer osgEarth for dynamic real-world terrain. -- Chris 'Xenon' Hanson, omo sanza lettere.
