New colors won't help with sloped bricks. When the user places a sloped brick in the model, they can only specify one color. The rough slope geometry has to be specified inside the brick using color 16, or it won't track the user's color choice for the brick. If we want to allow renderers to show the slope as being rough, the geometry in question has to be tagged in some other way. As far as I can tell, this could only be accomplished with a new meta-command.
I have nothing against creating a new meta-command for this. And even if I don't support it in LDView's 3D view, I would probably support it in its POV export code.
