If I were to do a redesign of the TOS Enterprise I would have it look similar to the NX-01 but still have a secondary haul underneath. I still think they should maintain from Jefferies' design though but I'm just explaining how I would design it if I was asked to do a redesign different from Jefferies'.
Today I too would use the NX-01 design elements to re-design the TOS-Enterprise, tomorrow I would probably use those of the new movie-TOS-Enterprise.
My tastes and interestes shift quite a lot in that regard. And I have no problem with up-dating an old design.
But then, the NX-01 is also a sore point for some here.
Shall I tell the new people here about the 'Conestoga-conspiracy', Cary
