As far as I know, the devs of this mod only really intend to add 3D versions of items already in the base game in future updates. That being said, they did introduce the katana, which isn't in the base game, so who knows what could happen.

The thing I want to see the most in the mod is fire/electric damage. Also, better throwing could be a good addition. I don't really have any items that I want in particular, though.
