There was little interest as there was little going on here. Most of the TWC-members are not really into programming and/or 3D-Modelling. Additionally many hoped for CA up to now.
And with no one telling he is working on it, it is a little boring to just check here and see poeple asking for progress into the blue.
The main question is, if someone is willing and able to work on such a converter. You might need some programming skills, but most of all i think very good knowlage of 3DS-skripts, as this seems to be the programm CA used. Mayby it don't need to be 3DSmax, but as i'm not really into 3D-modelling, i can't say.
