From what I can gather, the issue with the Anaconda is that is a full damage LOD applied to it, which none of the other ships do. As such, any skin for it would need to change it's properties as the outer hull of the ship takes damage. I suspect this will be quite a challenge from a coding perspective. Many, many things need to be looked at before this I suspect.
That said, I would really love some skins for my 'conda, I've run out of ones to buy for the Python.
