With the release of the new LGV route, I think it would be nice to have an ICE3 MF with TVM/KVB signalling to run on the route
True, they do have that and anyways the DB BR 406 ICE3M already exists, the problem (I think) is that real ICE's don't run on LGV Mediterranee, but rather on the LGV Est (Like Eurostar's mostly run on LGV Nord)
