My opinion on ships to use. First I am assuming no actual shuttle or similar ships, Runabout, Delta Flyer, even Starfleet 2 man attack ship/ Maquis Raider aren't technically shuttles.
TNG and TOS and Original films were limited by Model construction, so pretty much any original model that has real promise would get picked, as compared to later DS9, Voyager, or Enterprise, where ships were created for almost all races we were shown.
Also for myself this is Trek based on materials that would have been part of the art department and approved by executive producers (film and tv), not things like FASA (Loved them as a kid), not the old technical Manual, not novels and computer games.
TNG produced many cobbled together models from spare parts, redressed many models with minor differences, and even created some out of plastic and razors, which I also won't consider as in my mind they aren't serious work.
TOS
1. Original Enterprise (Will be done)
2. Romulan Bird of Prey
3. Klingon D7
4. SS Botany Bay
5. K7 Station
6. Fesarius (once mentioned and then later said not likely)
Those are the only TOS pieces that I could see making any cut due to lack of detail on others (like the Tholian ship of that time). But I would still get it.
TOS films
7. Enterprise Refit (Done and poorly)
8. Klingon Ktinga (Done)
9. Enterprise A (to be done)

TNG films leaves still several other options. The ships Guinan's people were on, The Stellar Observatory, Captain's Yacht, the Solar Collector, the Romulan/ Reman attack craft, the Holo ship.
DS9

64. Dominion Station
65. Daedalus class ship
Ds9 had several other options, from a huge number of kit bashed ships to various alien crafts of the week. Wouldn't mind the orbital weapons platform either.
Voyager
66. Voyager (Done)
67. Maquis Raider (will be done)
68. Kazon Raider
69. Kazon Carrier (large Kazon/ Trabe Vessel)
70. Array
71. Vidian Ship (if they must) Vidians only had redressed ships if I recall, but they were a major early player for Voyager, and one of the better designed races.
72. Voth City Ship (wouldn't mind the Medical City Ship in Critical Care either)
73. Bio Ship
74. Kremin Time Ship (Done)
75. Hirogen Ship
76. Dauntless (Done)
77. Malon Freighter
78. Delta Flyer (Done)

80. Borg Queen Diamond
81. Prometheus (Done)
82. Equinox (Done)
83. Raven
Voyager as a seeming less endless number of ships that could be used, some of really nice design, some utterly crap.
Ent

103. Sphere or Xindi Weapon
104. Nx-Alpha
105. Horizon
Enterprise had a large number of ships built for it and in many ways they showed a large improvement over the alien of the week ships built for Voyager.
So thats basically my wish list trying to keep almost entirely to well known ships, or ships that played important roles in major story lines. Or ships that were seen many times over.
And that takes us way past 90 ships, doesn't hit the new JJ timeline (though I think most of those will fail under specials, unfortunately, generally love the films with the exception of how little distance is shown and the design of ships, the earth station is an exception as well as the shuttle, both of those I really enjoy).
So without digging up alien of the week ships (with a very few exceptions), without mining the vast number of kit bashes that TNG and DS9 and Voyager used both model and cgi versions), and without doing duplicates of any nature. The film and tv universe as plenty to use.
Now I am not totally against outside ships (theres a ringship I would love, Love to see), I want to see them really use the full line up of material actually created and designed by the various art departments that were hired for the show first.
