My $.02 worth...
For the first two varients...
...the 1st would be the basic NCA...
1651 Chicago (Later refit to NHV)
1652 New York
1653 Dayton (Later refit to NHV)
1654 Los Angeles
...plus many others.
The 2nd version would make a fine NCD if the torp pod were changed to drones (the 4 B-racks; and could the rear of the pod be closed up?), and the top side torps (which this version dosn't have) be changed to drones as well (the 2 G-racks)...
1515 Azov
1516 Groznyy
1517 Gromykii
1541 Sverdlov
1542 Varyag
**********
Of the 2nd two varients...
...if the 1st were given an extra phaser to the p/s mounts, it would make a nice NCC (the torps being moved to the front of the saucer to make room for the flag bridge accomodations).
1655 London -Completed as NCC (+ 2 others, as well as a CLC converted. My personal list includes...
1660 Buenos Aires
1664 Calgary -renamed Indianapolis
1580 Clausewitz -renamed Dallas
As for the 4th varient with the full-sized 3rd nacelle, being the stickler that I am, I prefer the smaller nacelle. Although, this could be used as the basis for an NCF, which had 3 full-sizes nacelles.
**********
For a normal NCL, I would simply remove the 3rd nacelle from the first version (with the torps on top).
1500 Kearsarge
1501 Reliant
1502 Alabama
1503 Repulse
1504 Renown
1505 Prince of Wales
I would take Rod's version...
...add an extra phaser to the p/s mounts, and you have an instant CLC.
1580 Clausewitz -Converted to NCC design in '79
1581 Sun Tzu
1582 Jomini
1583 Tacitus
1584 Mahan
1585 Clancy
1586 Coyle
1587 Webber
For DarkMatrix's version...
...if the 3rd nacelle was re-added, and the changes discussed above for the NCD were done, it would make a great NDC.
1690 USS Crecy
1691 USS Terra Australis -refit NCD
*The hull numbers and the 2nd name are my additions
Lotsa possibilities here for all of the NCL/NCA varients from SFB.
