Gasy we do have a model for Chaillot which should be good enough:

We also have Beaubourg, although maybe a bit simplistic, but still better than nothing, and I think good enough:

There are also models for forum des halles and Versailles. None of the Versailles models were complete or satisfactory, they all needed work for sure.
As for les halles, there are two models (part 1 and 2) and I'm not sure if they make the whole thing, or the latest version or what, you may want to look. For the forum des halles, Tom will have to dig a hole in the ground, but he knows how to do that
I am compiling a list of models, that I will send to Tom to see which one he can use. Tom, I will add a location map, or maybe a KML if I can figure that one out.
