You may need to dull the speculars a bit. The studio model uses the same colours as the other TMP ships (That off-white/eggshell-white) as currently it's very ENT-era (Which is still cool, but if you're going for canon..) As for flipping the ship, the only difference between the Nash and the Jenolan is the registry format, if that's what you meant. Having the bridge upside-down would just look a little... Odd, I guess. Unless you take a little creative liberty and place the bridge-dome on the new "top".
