Wow, excellent! Truly a remarkable job. You've really redesigned the Hat and it looks great.
Texturing this is going to be a bit more difficult, though, since the modifications to the model alter the pattern set by the maps. Still, I think someone sufficiently talented could pull off something that might not be exactly like the original maps, but similar enough to be accepted.
Perhaps the one modification you might want to make is ensuring the continuous bands of lights along the neck can still be mapped in. They're a really distinguishing feature of the Hat, and as wonderful as your enhancements are it would be a shame if they were lost. It sort of reminds me of the bar that Bobboau put across the large square above the Orion's hangar; it interposed on one of the ships identifying elements and was removed.
