in OpenSG 1 basically the first material encountered (while depth first
traversing the scene) wins and determines the way everything below it is
being drawn.
The only thing I can think of is moving all Materials from the
MaterialGroups into the Geometries and replacing MaterialGroups with
just Groups.

If you could restructure your graph to have the Transforms above the
MaterialGroups you could add your highlighting geometry to that
Transform. Of course that assumes you have a lot of control over how the
graph actually looks, I don't know if that applies to your case.
Hope it helps,
