Alliance are a serie of different mods. On the Star Wars GC, you can play the civil war Empire vs Rebel era + Black Sun and soon the Republic and CIS.
I made by myself two new heavy cruisers for the Hutts following this image

Obviously the texture is only temporal, the final version will look probably more as the original image from the Hutt fleet.
great job!
As you already said it needs a complete retexture, but other than that the model is quite nice, maybe it needs to be a bit wider.
