Hum... it's a bit more complex in Soya, because the order in which the objects are rendered may not follow the scene tree. However, i think the new deforming system (again :-) can be easily extended to do that ; something like a MaterialSwitcherDeform. Instead of just "one-material inheritance", i'm thinking rather to a dictionary mapping old materials to the new ones, which would allow to change several materials. Basically, the deforming system create internally a "ghost" shape/model, which share some attributes with the non-deformed shape/model. E.g. for mesh deformation, it shares the materials list but not the geometry, but the contrary should be doable: sharing the geometry and display list, but not the material list.
