These two should be cake..... just a simple nacelle adjustment.
Aldebaran, U.S.S. Federation starship, Starfleet registry NCC-1812. (Technical Manual [Franz Joseph TOS]). This vessel is listed as one of dozens of future Constitution-class variants starships.Alioth, U.S.S. Federation starship, Starfleet registry NCC-1828. (Technical Manual [Franz Joseph TOS]). This vessel is listed as one of dozens of
future Constitution-class variants Though very vague a description, the fact it says "Future connie varient" opens it up to one's imagination so I decided on this as the varient..........

A still different slight variant had previously appeared in TNG: "The Neutral Zone", with the nacelle top sides facing outward and the rear end facing forward.Alferaz, U.S.S. Federation starship, Starfleet registry NCC-1781. (Technical Manual [Franz Joseph TOS]). This vessel is listed as one of dozens of future Constitution-class variants.
Alfr, U.S.S. Federation starship, a cruiser type vessel, Starfleet registry NCC-1741. In 2289 the Alfr went on an exploratory cruise, in the company of the starships Atalanti, Noshiro and Essahir. (Technical Manual [Franz Joseph TOS]; Ships of the Star Fleet). This vessel is listed as one of dozens of future Constitution-class variants.
